The examples are based on finding hysteresis width, upper and lower threshold of Schmitt trigger as well as the design of Schmitt trigger.
The timestamps for the different examples covered in the video is given below.
0:26 Example 1
6:01 Example 2
9:24 Example 3
14:37 Example 4

for example 2, the hysteresis graph for non-inverting schmitt trigger is wrong right?
4V for 10%duty cycle
My man, you’re a life saver
Have my exam in 8 hours. You've got me all covered. thanks a lot!!!!!
i believe the transfer characteristics at 9:10 is for the Inverting schmitt trigger and example 2 is based on non-inverting.
Agree with you.
Yes bro
You are awesome guru .I never ever get this much addicted to any channel.Only you thank u and luv u so much❤.This channel help me a lot to learn DLD .
6:00 Duty cycle of 10%is 4V
Yupp
intresting example ...tq sir
Good examples !
When I got to the Schmitt trigger videos I said to myself "Oh good, some easy ones" But, nope. I had trouble doing the problems. Maybe next time going through it will sink in better : ) Your subcripitions are increasing quite rapidly, you deserve it.
Excellent!!!!
keep doing the good work
thank you dear!!!!
Thank you sir
Great explanation for schmitt tirgger in series video. Thanks a lot. What is your name and do you have any book in english?
Vref =4v , Ton =2ms
Vref=4 V for 10% duty cycle
in example n3 when you use kcl, which generator do you consider working 3V or Vout? Thank you
How to solve Qs of Opamp involving both positive and negative feedback??
Anybody else notice that all variables (high, low, 50%, 25%) sound like a recorded sample of his voice (i.e. identical and monotone). Surely, he's not cuing a sample every time he says "low". Good video btw.
Hello,
Would You explain to me, how did I get shift of transfer characteristics, for example: VH=2V, VL=-3V (not -2,5 and 2,5 as usual)? How is this possible?
I've been using Hall sensor with Schmitt trigger for multipole magnetic encoder and on the output I got signal with 1/3 duty cycle, instead of 1/2 duty cycle (poles are equal, but reverse in sign).
Does transfer characteristics shift depend on Vref? How did we get Vref - I mean once per measurement (on the every begining of each multipole encoder measurement it takes valuse dependent on first pole it measured and it is constant through whole measurement) or every time we cross VL or VH threshold? Does characteristics shift constant through whole measurement (if it is) or does it change every time we cross VL or Vh threshold? I would be very greatful for Your response!
example 2 transfer characteristics curve is wrong
Example 4 is non inverting schmitt trigger, on comparison earlier when you had taken Vout=VL, it was V+
Veryyyyyyyy Niceeeeeeeeeee
Ton- 2ms Vref-4V
Accurate approach .sometime use Hindi notations also.
no
vref =4v
really a good problem..........
at 12:00 should the output voltage not be -15 since its inverted ?
Hi in the last Example you choose when V+>Vref then Vout=VL
Isn't this non-inverting amplifier which in your previous video said when V+> 0 then Vout=VH
can you sxplain whats the differance
For the last example covered, Isn't R2/R1= 3 If we calculate by considering that VH doesn't depend on VR...So, VH=5(2 - - 3)Please help!!!!!!!!
kindly tell the name of software used by U for writing
In EXAMPLE 3, is there any way that the +3v source can be a simple 3v resistive divider?
THANKS AGAIN!!
I am recommending you highly!
Yes, using resistive voltage divider you can generate 3V.
Can I assume a value for upper threshold voltage if the resistance values are not given and only Vcc is given.
It will get very random to assume.
hey, in the last example, since there's a Vref wouldn't the transfer characteristic graph shift left?
If you see, because of the reference voltage, the transfer characteristic is not symmetrical. (-3V and 2V). The effect is already is taken into account.
Vref=4v and Ton 2ms
How can be Vin>V+ if Vo =+15v? @23:07 timing
I think you have mistaken V+ as the positive supply rail voltage. It is the voltage at the non-inverting terminal.
👏🔥🔥
the transfer characteristic for example 2 is given in video to be inverting but in question it is non inverting hence transfer characteristic is incorrect
Nice
ans at 5:59 is 4 V
4v for 10% duty cycle question.
Sir which % we take for duty cycle high or low???
High
4 volt for 10% of duty cycle
+4 Volt for 10% Duty Cycle
21:52 here the eqs are not correct as they won’t satisfy same unit(voltage) on both sides and r1/r2 is not v. I have doubt sit
4v for 10% duty cycle
How do you decide on taking Vh or Vl for Vut and Vlt? Does it differ for both configuration (ie) inverting and non-inverting Schmitt trigger?
Yes, it depends on the Schmitt Trigger configuration (Inverting or Non-inverting).
In case of inverting Schmitt Trigger, when input crosses Vut, the output becomes low voltage. While in the case of non-inverting Schmitt Trigger, when input crosses Vut, output goes high.
More more information please check my video on Schmitt Trigger. Where I have explained it with the transfer characteristics.

Can we do for example 3 like treating circuit as without reference so we got 5 V as UT and -5 V as LT and after adding reference +3 V so we got 8 V as UT and -2 V as LT , So my question is could it Work or not because answer is not same..??
It won't work that way.
@@ALLABOUTELECTRONICS Thanks
For 10% Duty Cycle the Ref. Voltage is 4 Volts.
how?
I am first
Is voltage signal different from current signal?? Thanks in advance.
Yes, both are different.
transfer characterstics of expample 2 is wrong guys
4v
4v for 10%
When will be the next videos going to upload
probably in 2-3 days.
ALL ABOUT ELECTRONICS sir when will be available, 2-3 days gone?
Probably tomorrow in the morning.
4 volt ref for 10% ?
Correct. The 4V reference voltage for 10 % duty cycle.
ALL ABOUT ELECTRONICS ty sir your work is great keep it up
4 v
.
Not interesting as we think
4V for 10% duty cycle
