Remarkable..... I've been into electronics (professionally and as a hobby) for over 40 years, and I've never heard such a clear and concise description of filters like this. You, sir, are a gem to the hobbyists and DIY'ers. I am seriously considering joining your patreon to help you continue your series, as well as other projects you might venture into. Please keep up the excellent work and dissemination of this information.
You really have a talent for explaining. I always wondered how my synths actually work, but I couldn't find a source that was deep enough, yet understandable enough without a background in electrical engineering. I think you've successfully hit that sweetspot. Keep up the good work! Thanks!
I've been fascitinated with filters and dipping my toes into DIY now. I knew a mix of resistors and capactoiors create filters, but I always wanted to know how these two componots remove frequencies. Your video finally taught me, subscribed!
Your channel is a treasure trove to me. I have been tinkering with electronics as a child, and later when I got into music production, I wanted to learn how circuits can generate and manipulate sound. I searched all around, but never found something that truly satisfied this longing in my soul. I wasn't so interested in blindly building these circuits, I wanted to know why they were designed that way, and why they worked. A few months ago, I found your video on building a compressor and after I watched it, I knew that I had finally found what I had been looking for. Thank you for these videos, you rock!
Oh my God dude, I've been trying to understand this for 3 or 4 years now after going to school tomget electronics degree , I ran into the exact problem you stated at the beginning your pipe and balloon method just helped me understand this more than my studying in the last half decade. Your an amazing teacher man , another vid going in to my pouch
Wow thank you!! This was really good made and understandable. Did not have the components at home, but a single capacitor. Was just holding it between two mono jacks, a cable between the ground and there was a high pass 🤩🤩🤩
Lovely explanations! One minor nitpick though - filter cutoff frequency is not where the filter starts filtering, it's where the signal has already dropped off by 3 dB from the passband unity gain.
Damn, your ability to convey all of this knowledge in your videos is outstanding. But something I don't think you get praised enough for is your aesthetic- the lovely wood table, the clean drawings to accompany every explanation that helps the learner visualise all of these concepts, the little electronic components scattered around the edge of the screen... It's beautiful. your videos are so aesthetic
Your videos are incredibly effective and enjoyable to watch. Please keep doing what you're doing, you're super successful at supplying knowledge to thousands of enthusiasts around the world.
Great storytelling... love the pipes, balloons and pressure analogy to describe how components and circuits work. Well worth following or bookmarking this mini series.
Hey man, the placement of components on the left and right side of the paper was a friggen excellent composition choice. The quality of the video is so high that it almosts looks like you are looking at a powerpoint with borders and art. It's fascinating.
By far the best and most educational lesson on how filters work I've ever seen anywhere online. Very well explained, and even if I didn't already have some basic understanding of electronics, it would have been easy to follow. Well done. This may now be my favourite CZcams channel after just watching one video.
So increasing r makes less current get to that capacitor and thus the capacitor fills up more slowly, and because it’s filling up slower then it can absorb pulses of voltage that are longer (lower frequency waves) as r increases. Correct? Thus it’s not really practical unless the output is actively amplified in an inverse relationship to amount of r?
No kidding, great videos! Finally, someone that doesn't present a bunch of formulas, I have those. Watched a recent video of classical musicians, instruments in hand and ready to go, listen to a basic theme. A blues musician started playing along, but the orchestra was baffled. No sheet music. I felt embarrassed for them. The blues guy "understood."
These videos are so wonderful. Great level of explanation for those of us with familiarity with what filters do but not how they work. One of the hardest parts of explanation is estimating the level knowledge your audience has.
Very cool explained. I think you once said that you're not a professional, maybe that's why you are able to explain it so that amateurs can understand it. Before finding your channel, I often watched GreatScott but he sometime's too short cut with his explaination. More like, take this chip look in the data sheet that means we can do this and that and then it works, while you explain it really on the low level what I especially like because I find it easier to understand when I really can "see" (even if it's water analogy - that's certainly not always 100% physically correct but much much easier to understand for the normal person) what's going on in these thingies. Please keep up the great work with these videos!
thanks, very glad you like the videos! and yeah, i mean i'm basically learning about most of these things as i make these videos - i guess that's why i'm being extra-beginner friendly!
Your videos are helping me a lot with learning electronics for building guitar pedals ❤ The hand drawn diagrams explanations stick in my memory better than other stuff (electric guitars are synths 😱🎸🤫)
I actually just tried this. When I watched this, I wasn't actually thinking of making a filter, but I wanted to make a passive slew limiter for a MIDI to CV converter that I recently built as a DIY kit, and of course this works as a simple slew limiter too. A low-value resistor (around 100 Ohms) and a capacitor somewhere between 10 and 40 µF seems to work great to smooth out the edges of CV outputs which would otherwise have had 128 discrete values, making it sound very harsh and digital. So much easier than any other schematics I've found for slew limiters. Thanks again.
This is a great explanation! In the past I have also used the idea of a voltage divider with one resistor and one capacitor, where the capacitors resistance is frequency dependent. This has also worked well as long as I have explained a normal voltage divider first (volume control), but I think I will steal your balloon analogy for future use! :)
I've been building my own synth from scratch for 2 years now. I had no background at all. There is a lot of usefull info on the internet but this channel is super clear and educative.. Thanks a lot!
I'm so glad I found your channel, these videos are really interesting. Your explanations of these concepts are so clear and concise it's easy to follow and I have learnt so much from just watching a couple of your videos. Looking forward to watching them all. Thank you.
I have been looking for a good channel about diy modular synths for ages. Now I finally found one, so I subscribed instantly. Please keep these series of videos coming! They are really the best pieces of information about diy modular synths out there.
Fantastic information! Been going through your other filter videos and while I'm vaguely aware of most of this from my Uni, your videos truly make things click and make audio filtering and the formulation behind it really make sense. Truly appreciate your efforts! Keep it up!
Glad to find your channel, I've been wanting to get into building synths and didn't know where to start, but your videos have demystified a lot concepts for me.
This is superb. I can't thank you enough for sharing your knowledge. I'm sure it takes a great deal of time to develop and produce your videos. you have my gratitude. Very much looking forward to the continuation of this series. I got into electronics so that I might build my own filters, but have yet to find a sufficient resource to facilitate my achieving such a goal... Until now. Thank you again. And again... Several more times. :)
I was learning how to make my own hardware equalizers and compressors and then I stumbled upon this. I just want to say what an excellent analogy and teaching style you have. Kudos, please keep making this, I would love more hardware plugin related lessons as well.
Wow fascinating analogy. That's about two undergraduate courses worth of material and I used to teach some of this. The high pass filter I would explain by the capacitor charging and discharging.
I love your drawings. Your illustrations are far more clear and understandable than my electronics professor's scribbles. LOL. Thank you for your circuit explanations.
During uni I always has a hard time trying to come up with an analogy for capacitors and how they interact with the circuit with sudden voltage changes especially with oscillators. These analogies really help in building my intuition and hopefully make me a better engineer in the future. Thanks for these videos
I've watched almost everything youtube had to offer in terms of D.I.Y. modular synth video and your videos are the clearest and most accurate I've been able to find so far! Thank you so much for all the great videos you are sharing.
thanks for the video man, i appreciate it, i'm in a different field of study but it coincides, i'm an auto tech and hade been making filters for automotive ocilloscope diagnostics, actually working with very low frequencys
Thanks for the clear video. I have to mention that passive filters can resonate though. For instance a simple RLC displays resonance for some values of R, L and C.
thank you for doing this series, I already builded your VCO and it's sounding great! , your videos gave me the confidence to finally start building my modules.
These are both nitpicks, this is an excellent video: One thing is missing from your capacitor-balloon analogy: the absolute voltage of the ground plane. It's like sticking the end of the pipe with the balloon into an infinite swimming pool. The static pressure of the water outside the balloon (directly related to depth) is analogous to the potential (relative to infinity) of the ground plane. That's part of what's balancing the pressure of the water inside the balloon, it's not just the elasticity of the balloon. This would also aid your explanation of why you need to connect the grounds of the VCO and the filter together. When you drew the transfer function of the passive RC filter, you placed the cutoff point far inside of the normal -3dB definition of cutoff. Maybe you were intentionally placing it at the -0.1dB point, but AFAIK that kind of tolerance is generally reserved for telecom stuff operating in the MHz/GHz.
you're completely right about the balloon analogy. in my VCO video, i actually explained it the way you did. got lazy here and cut corners! one thing though: i do think the "elasticity" plays a role, doesn't it? at least that's how i conceptualize the fact that while the capacitor is empty, it's easy to push current in, while it then gets harder exponentially the fuller it becomes. also, the cutoff point sheet is really crude and eye-balled and should not be taken as anything more than a visual metaphor!
@@MoritzKlein0 Hmmm... Now that I'm really thinking about it, I may have been wrong about the elasticity analogy being flawed. I may have been imagining a compressible fluid when I wrote this comment. My mistake! If we assume the water is truly incompressible, then I think the elasticity of the membrane would be akin to the dielectric constant, and the ultimate strength of the membrane would be akin to the breakdown voltage of the dielectric. I think the disconnect occurred because I tend to imagine electrons as a compressible fluid in rigid plumbing, as opposed to an incompressible fluid in flexible plumbing. In this case, I think I mixed up the two analogies and imagined a compressible fluid in flexible plumbing, confusing myself. Damn you, physical metaphors! Ultimately I think it's a combination of the elasticity of the membrane and the static pressure on the other side that determines how difficult it is to push electrons in, and I have edited my original comment to reflect that. This is truly an excellent video. I hope you continue to make easily accessible content like this, because a lot of this information is difficult to find outside of a university, and even more difficult to learn. Even for someone who's seen all these concepts before, it's still a great way to stretch the brain.
Thank you so much. I love Sam Battle's (Look Mum No Computer) for his whimsy and simplified, use this/ do that and this will happen. I love your practical knowledge and examples. I have learned a lot and so far the tones you are generating and Sam's tones are musical and not just noise. Thank you. Keep up the great work.
This video is great!! I can't wait to learn more!! I can only think that you will have more videos and include things like envelope filters and ADSR!! CAN'T! FRIGGIN! WAIT!! Thanks again.
Another excellent video! I've been building guitar effects pedals for a while now and am just about to get started into bread-boarding some circuits based on fuzz/filters. Stumbling upon your youtube page could not have come at a better time! Well done on the great content. I've checked out some other instructional videos - more dedicated towards guitar effects than synth DIY, but few have been so well put together and explained. You have a new subscriber.

Thank you for this series. You are really good at explaining how and why these circuits function the way they do. Great stuff keep it up.
These are both nitpicks, this is an excellent video:
One thing is missing from your capacitor-balloon analogy: the absolute voltage of the ground plane. It's like sticking the end of the pipe with the balloon into an infinite swimming pool. The static pressure of the water outside the balloon (directly related to depth) is analogous to the potential (relative to infinity) of the ground plane. That's part of what's balancing the pressure of the water inside the balloon, it's not just the elasticity of the balloon. This would also aid your explanation of why you need to connect the grounds of the VCO and the filter together.
When you drew the transfer function of the passive RC filter, you placed the cutoff point far inside of the normal -3dB definition of cutoff. Maybe you were intentionally placing it at the -0.1dB point, but AFAIK that kind of tolerance is generally reserved for telecom stuff operating in the MHz/GHz.
you're completely right about the balloon analogy. in my VCO video, i actually explained it the way you did. got lazy here and cut corners! one thing though: i do think the "elasticity" plays a role, doesn't it? at least that's how i conceptualize the fact that while the capacitor is empty, it's easy to push current in, while it then gets harder exponentially the fuller it becomes.
also, the cutoff point sheet is really crude and eye-balled and should not be taken as anything more than a visual metaphor!
@@MoritzKlein0 Hmmm... Now that I'm really thinking about it, I may have been wrong about the elasticity analogy being flawed. I may have been imagining a compressible fluid when I wrote this comment. My mistake!
If we assume the water is truly incompressible, then I think the elasticity of the membrane would be akin to the dielectric constant, and the ultimate strength of the membrane would be akin to the breakdown voltage of the dielectric.
I think the disconnect occurred because I tend to imagine electrons as a compressible fluid in rigid plumbing, as opposed to an incompressible fluid in flexible plumbing.
In this case, I think I mixed up the two analogies and imagined a compressible fluid in flexible plumbing, confusing myself. Damn you, physical metaphors!
Ultimately I think it's a combination of the elasticity of the membrane and the static pressure on the other side that determines how difficult it is to push electrons in, and I have edited my original comment to reflect that.
This is truly an excellent video. I hope you continue to make easily accessible content like this, because a lot of this information is difficult to find outside of a university, and even more difficult to learn. Even for someone who's seen all these concepts before, it's still a great way to stretch the brain.
Wooooow, I always wanted to how a Moog ladder worksss, this is perfect!
That was a beautifully simple explanation and examples on filters!
Brilliant! Thank you!
Can't belive this is free contant! Wundergoldig!!
Thank you so much. I love Sam Battle's (Look Mum No Computer) for his whimsy and simplified, use this/ do that and this will happen. I love your practical knowledge and examples. I have learned a lot and so far the tones you are generating and Sam's tones are musical and not just noise. Thank you. Keep up the great work.
This video is great!! I can't wait to learn more!! I can only think that you will have more videos and include things like envelope filters and ADSR!! CAN'T! FRIGGIN! WAIT!! Thanks again.
best lesson in youtube
plz keep doing these videos it's my favorite yt channel
These. Are. Gold!
Another excellent video! I've been building guitar effects pedals for a while now and am just about to get started into bread-boarding some circuits based on fuzz/filters. Stumbling upon your youtube page could not have come at a better time! Well done on the great content. I've checked out some other instructional videos - more dedicated towards guitar effects than synth DIY, but few have been so well put together and explained. You have a new subscriber.
glad to hear! next episode’s design should actually be fairly usable for a pedal - even without voltage control.
@@MoritzKlein0 cool! Was already researching a 9v filter based on the ms20 that was drawn up by Tim Escobedo I think. Will be good to compare!
This is very well explained 👍
Thank you for an awesome video.
This is incredible
You've created a valuable resource here, thank you so much!
Wow. This was incredibly informative. Well done!
