I don't usually write youtube comments. Yet I have been looking for this kind of video for a very, very long time. Usually the videos similar to this do not explain much about the circuit - they just hand it to you. I have found many videos that explain AM, yet this is the one with many examples, so that I can clearly see what is going on. I really loved the part where you divide the big circuit into smaller parts. Liked the video. Subscribed. Did everything that is in my power. Cheers <3

this video was way ahead of its time.. Clean simple easy to follow. Didn't know until the end that this was posted 9 years ago.

As EE student, I must take many courses relate to digital communication, wireless communication, electromagnetic wave, analog circuit, etc. We have lab after lab to prove a ridiculous amount of theories and yet not a single lab like this. This is the first time I see all those theories we study come together nicely and do something useful in real life. I think the school should teach us how to walk properly down on the earth before they slap the Icarus’ wing to our back and demand us to fly high!

I want to thank you for this video. I'm a scientist (in comp sci) and have spent days looking through technical articles trying to understand basic RF concepts This video finally did it for me!
-
probably one of the most informative videos I've seen on an actual application for modulation.
-
The best video on radio transmitter. Lot of easy to understand information, in a very short span.
-
Thanks Afrotechmods, that's a terrific example of how to impose information into the carrier, thankyou, looking forward to more, people like you are pretty special for sharing your knowledge so others can learn. best wishes.
-
this is the most informative and intriguing video i have ever seen
-
This explanation was just amazing! Thank you very much!
-
pretty awesome. i was looking for something like this several months ago, surprised i didn't stumble on this video then. thanks

@Afrotechmods AM does pick up interference, but is much better for covering mountainous terrain than FM, which is strictly line-of-sight and will get blocked by terrain. I live in a hilly area between two major cities, and I have to keep switching my FM presets depending on which side of the mountain I'm on, whereas the AM stations from both cities can be heard equally well throughout the area. (Although this is mostly due to the frequencies used by the AM & FM bands, not the modulation method.)

Thanks for putting this up, I need to make a high frequency oscillator for an experiment I want to try, and this looks like it might work in my experiment.
-
great thx man your videos are really doing a great job! i am a newbies in electronics devices, but your videos are making them much more easier to be understood!
-
Phenomenal video man, talk about making sense of black magic!
-
Great explanation! Thanks for sharing.
-
So cool video! Great work! I will feature it today in my site. Looking forward for your next work
-
I'm still confused how modulation works but after watching this video, I got enlighten somehow. Thank you, sir, for this video.
-
This is a well produced video.
-
Thank you so much for all this informations!!! I really enjoyed it!
