Amplitude Demodulation


    Sep 24 2011 | 11:51 am
    Hi all, does anybody know of an existing external or patch, that does Amplitude Demodulation ?
    I have a low frequency signal (around a few Hz) and amplitude modulate it by 10.000 Hz.
    Now I want to extract the original signal from the AM signal.
    Any help or link is well appreciated!
    Thanks, Frank

      Hi Frank I tried doing this with math-tilde objects ([/~] etc), but eventually settled on the old Renaissance algorithm known as "cheating":

      maybe something like this?

      btw - the initial phase value of the rightmost cycle~ should be 0.5 (set the float connected to the right inlet of cycle~)
