Happy Learning : )
This was really a great experience. I think this system of showing body language and expression will grab our attention very much.
Listening in all the way from Fiji. Appreciate the basic explanation of the block diagrams and easy to understand.
MAN THIS WAS THE CLEAREST EXPLANATION ✅
clear and simple explanation!
I cleared analog communication just by your lectures...
thank you

Yaar literally what a personality, i was confused that she is a kid ,, but great teaching, thanku
same she saved me the day before my exam
Thank You So Much Mam❤
It was very simple and clear ❤😊
Mam thank you so much 🙏your teaching skills are amazing 😊
For RF amplifier its not so much that is "selects" the desired frequency but more so that it improve the SNR of the desired signal more than the surrounding noise. Selecting a desired frequency is more often done by band pass filters which allow only a specific range of frequencies and tunes out the frequencies that are outside of the desired range.
NYC explanation, easily understandable
It worked thank you ❤💥
Mam your explanation is great 😊👍
Tqsm sir nice explain
Thank you ma'am
Great explanation
Excellent Teaching Mam ❣️
Yours teaching was well ma'am
Thanks from kerala🎉🎉
Anteena also acts as a frequency selector due to its resonant characterestics
Best class ❤
Very nice ly explained..
Very good👍👍👍 explain
Awesome 👍
thnk u maam for this helpful video.. does this is applicable for communication radio sets? why do we use two IF in radio sets for communication purpose in receiver module

Madam tell what are the faults occurs in this process....if local oscillator frequency is higher than rf frequency...or local oscillator frequency is lower than rf amplifier tell me other fault in this whole process
Thanku sister
Thanks ❤
today my all doubts clear regarding super hetrodyne rx
Helpfull👍
Tomorrow exam 😢
Us bhai us😂
Also me too bro

Thanks for the video. How will this receiver type handle a signal at the level of MHz? I wish you would give clear numerical examples. For example, let's assume that a 100Mhz signal is coming from the antenna in the FM band. How will the stage amplifier after the antenna amplify this high frequency? There isn't even a transistor to handle a 100Mhz signal.
Kindly download the Ekeeda Learning App ekeeda.com/download.html & ask your doubts. Our experts help you to resolve queries on chat.
That is a block diagram. within each section you find the actual electronic circuitry with resistors, transistors, capacitors, etc.
Nice video mam tq 😍🥰

Can you make a vedio on Hetrodying
Thank you madam
Nice
Miss, Why do we need to convert the received RF signal to IF signal?
We need to convert ti to fixed IF (such fixed 10,7 MHz or 455 kHz) because it would be a lot of undesired harmonics when tuning the scale on VHF from 87,5-108 MHz through many amplifying transformers and when amplifying this range frequency through transformers for amplifying and selectivity, there would be a lot of undesired harmonics on each different frequency tuned, that is why you convert it to fixed intermediate frequency (IF) and then you work on it for selectivity, limiting, amplifying, demodulating.
