Hi all
Perhaps my question is stupid, but I am momentary at the end of my ideas. What the heck is the demodulation of AM if I have a I/Q signal ?
My homebrew HDR-2005 (= HardwareDefinedRadio 2005 is a mixture between QRP2001, SDR-1000 and other concepts. It sounds great in SSB.
I demodulate LSB, USB or both but not AM. Yes, yes I know M = srt(I^2 + Q^2), but how I do it in hardware ! Up to now all my trials with AM ended in much distortion.
Does anybody knows how I produce a clear AM from I and Q with (analog) hardware?
Best regards
Chris

... for a extensive discussion of AM-I/Q look at

How do you join that group or see the posts? that link says "You are not a member of the group soft_radio. "
