Calculate R and C in Envelope Detector Circuit (AM Modulation)

[QUOTE="rude man, post: 6306418, member: 350494"] OK. Basic idea: the time costant should be large enough to smooth out the output as much as possible. BUT - at the same time it must be small enough to see variations in the carrier amplitude if that amplitude is varied by the modulation signal. So there's a tradeoff here. How about picking the time constant such that the modulaton amplitude is down 3dB at ## \omega_m ##? What would be the ripple output voltage given ## \omega_c ##? [/QUOTE]
