Hi, i have 2 questions, 1)How ratio of Am/Ac impact the difficult of choosing the RC time constant in the envelope detector? 2)How ratio of fm/fc impact the difficulty of choosing the RC time constant in the envelope detector?
One important note is that connecting LPF directly to Envelope Detector without proper signal isolation changes fundamentally the behavior of both. Also for the Load directly connected. Ideally you want to isolate the the modules Input and output from the signal filtering. One way to achieve this is through a simple source follower OpAmp configuration.
You are amazing! Thank you so much for your work, it's increadible how simple you can make complicated subjects. I even liked the video before I started watching it and now that I have finished - I'm very happy I did.
I agree, this is a super helpful and excellent video!!! I would love to see you do the same thing for FM ratio detector!!! Thank you for taking the time to make this.
❤excellent . Just loved it. Keep more good work like this comming please. Jai Hind. What simmulation software have you used to detect output across load?
Yes, will definitely consider that suggestion For many videos, I have already provided notes. Please check the website : www. allaboutelectronics.org Will update more notes soon.
The change in amplitude is our message signal or information signal. And that's what we want to recover. Whether we will be able to recover it or not, it depends on the RC time constant of the filter. If the RC time constant is too high then filter won't be able to detect that. I have already mentioned that condition in the video.
Hi friend, thanks for the mini lecture on this. I am starting on an AM receiver project. The only things is that the frequency I want to use is actually just higher than most FM radio broadcasts, and it is in the VHF band from 118-137 MHz. I am trying make an ATC scanner to listen to planes overhead of me. Any tips in choosing an RC value while rectifying?
Best video sir...but i found little difficulty in how dc filter work and what is the frequency of output comming before low pass which is less than low pass filter1.59.
The message signal frequency is 1 kHz. That means low pass filter cut-off frequency should be such that it should pass message signal. In other words, it should be more than message signal frequency. In this case, since it is 1.59 kHz, it will allow the message signal to pass. I hope it will clear your doubt.
Ripple is basically high frequency component in the signal. The low pass filter passes the low frequency components and removes the high frequency components. So, the low pass filter can remove the ripples from the signal. I hope, it will clear your doubt.
Such a cheep receiver! Your transmitter is super cheep too! Would you use something like a phase shift oscillator for the transmitter? That would bring the component count down a ton not including amplifier stages. You probably need one amplifier after the oscillator to get your modulation index/add the signal and it’s carrier. Some filtering at the antenna would be good as well
Hi sir, I like your vedio very much, but I am a new hand of Multisim, my version is 14.2, I can't find the easy using interface in your vedio. Could you give me some instructions about my issue? Thank you verymuch!
In low pass filter with proper cut-off frequency, the capacitor is charging slower than the ripple. So, in this way, ripple won't appear at the output of the filter. I hope, it will clear your doubt. I have also shown simulation. Please go through it.

This is the best explanation of envelop detection available in YT. And the simulation has just blown my mind. Thanks a lot❤️❤️
genuinely great explanation, simulation, drawing, presentation, and everything! Thank you.
you tube always better than professor.

Ideally you want to isolate the the modules Input and output from the signal filtering. One way to achieve this is through a simple source follower OpAmp configuration.
Yes.
Adding a non-inverting OpAmp after the LPF is essential. That makes it an active LPF instead of a passive LPF.
Oh god, this guy works very hard. Excellent explanation in great detail, simulation is also shown. really appreciable.
You are amazing! Thank you so much for your work, it's increadible how simple you can make complicated subjects. I even liked the video before I started watching it and now that I have finished - I'm very happy I did.
Thanks a lot for your super-intuitive explanation which is even much better than what my lecturer did!🥰
Excellent explanation.. best video I have ever seen on this topic 👍
your explanation is very clear, all the best sir, keep going
I agree, this is a super helpful and excellent video!!! I would love to see you do the same thing for FM ratio detector!!! Thank you for taking the time to make this.
You are GOAT (greatest of all time)
Excellent explanation!
Great explanation ,very clear. I hope you would make videos about FM demodulation or detection.
Excellent depiction. Thank you so very much.
Thank your sir for the simulation it was very helpful. I understood the -ve clipping and diagonal clipping better through the simulation :)
Excellent as usual
Waiting for more ❤️
Great job and very well explained.
If I could give two likes to this video I would, excellent content!
Very nice illustrations,. Thanks
Very good explanation , thankuu sr👍🏻👍🏻👍🏻
Beautiful! Such a Great Lesson!
great explanation as always, thank you sir.
Thank you so...... much Sir
Excellent Explanation....
waiting for your other videos
Excellent explanation
Really helpful.. Thank you so much..And best of luck..💜
Nice Explanation Sir
Great explanation ✨✨
Thanks !!
thank you very much sir for this video
I study in IIT Bombay and I admit, this video is absolutely amazing
❤excellent . Just loved it. Keep more good work like this comming please. Jai Hind. What simmulation software have you used to detect output across load?
It's a Multisim.
Very good explanation, thanks
Super explaination sir👏👏
Thank you so much it is helping a lot. A small request is that while making the video it would be nice if you could post the notes
:)
Yes, will definitely consider that suggestion
For many videos, I have already provided notes.

wowwwwwwwwwwwww man what an explaination
Nice explanation . But why is the amplitude changing as it passes through the low pass filter?
The change in amplitude is our message signal or information signal. And that's what we want to recover. Whether we will be able to recover it or not, it depends on the RC time constant of the filter. If the RC time constant is too high then filter won't be able to detect that.

Superb ☺
Beautiful.
thanks for the videos. Job well done. Is it possible to have access to the notes and also do you have a course for digital communication?
You are the best 👌🏻👌🏻🌈
Thank you so much 🙏
At 09:46 your filter is high pass filter not low pass filter. Look at your BOD diagram
I have mentioned High Filter only, please check it again.
Best video sir...but i found little difficulty in how dc filter work and what is the frequency of output comming before low pass which is less than low pass filter1.59.
The message signal frequency is 1 kHz. That means low pass filter cut-off frequency should be such that it should pass message signal. In other words, it should be more than message signal frequency.
In this case, since it is 1.59 kHz, it will allow the message signal to pass.
I hope it will clear your doubt.
How the negative half cycle is attenuated??? You have not mentioned where it is occuring
Still do more videos on engineering topics
are you using a any software to generate those sinusoidal signals? Great video by the way
Multisim- it's free to use
Good one👍
U r great. boss
how does the low pass filter remove the ripple `?
Ripple is basically high frequency component in the signal. The low pass filter passes the low frequency components and removes the high frequency components. So, the low pass filter can remove the ripples from the signal. I hope, it will clear your doubt.
What is the name of application you used for simulation?

Do you have a suggested type/model of diode?
Also, are the capacitors polarized?
