Amplitude Demodulation

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”:

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