Hello Matthew, just like to say really fantastic series on Introduction to Radio. I must admit I needed to replay part 4, 5 & 6 several times and go off to research some technology which without your course just wouldn't make sense and fit together. Really a wonderful series and unique because you really breakdown the science and not just rely on jargon and terminology. Thank you!!!
Hello there,,! I've listened to your lectures about the A.M receivers all at once,, and it made me to sit and listen passionately. Thanks for uploading.
Excellent explanation, I have spent years and read thousands of texts based on how antenna receiving really works but never made complete sense. This video series is by far the best in explaining it and now it makes complete sense. Antenna theory always seemed something more complicated than rocket science to me. Thanks.
Yeah... this was another excellent presentation, although I hedged somewhat about anything, including the hf stuff, passing thru the capacitor to ground, despite its acknowledged lower apparent resistance (inductance). Thanks again... best and most concise explanations I've come across.
Well one could say you are filtering the lower sideband away with the diode turned this way, and sampling / converting the high frequens into low frequens to be heard via the speaker.
If the detector is supposed to be a low pass filter, why is the resistor not set up as a voltage divider with the cap? Since the speaker and the cap are in parallel, won’t they both see the same (unfiltered) voltage input?
Absolutely fantastic series, thank you. Could you let me know what book/s you would recommend, at this level, so I could continue to learn about basic AM and FM radios. I think I have found a new hobby.

This video you've made here has helped me to find the peace of mind that I've been searching for so long. Lacking words to express my gratitude..

really, the explanations you give about this simple AM receiver are the best over the internet. Kudos ( and I'm an EE engineer)

so typicall in electronics, circles never close, until you find a superb explanation....

his explantion is wrong....when the currnet after diode hit the capcitor...the first plate is negatively charged and not positive..

May I ask what the purpose is for the resistor in the detector? What would happen if it was removed?
I think it would just fry the circut
