Hey, I was wondering if any of you smart people could help explain in a very simple way (if possible) how the first FM transmitter and receiver worked?
I know, for example, that many current transmitters use a voltage variable conductor to change the frequency of the wave. Did Armstrong do that in 1933? I have tried to read his patents but I don't get it.
Also, did he use a superheterodyne method or a heterodyne method to receive the FM (or some other method)?
Thanks so much!
