Looking for ideas, a lot of designers on this list have been there and
done that. so.... What do you recommed for the following:
Carrier frequency: 60 Khz
Modulation frequency: 1 - 10 Hz (square wave)
Type modulation: Amplitude shift keying (10 db RF change)
RF level: low (1 - 10 microvolts)
Receiver design: TRF (solid state)
Ideal circuit would be as follows: 60 khz modulated signal input with
two outputs. Output 1: 60 khz carrier stripped of modulation
Output 2: Modulated signal (square wave) in sync with zero
crossing of the 60 khz carrier
Cost: Lets say maximum of $2 for all parts.
Lets start the new year with a design thread. :-)
