Hi,
For my A2 Electronics project I am attempting to use a Pulse Code Modulation system to transmit an audio signal wirelessly across a small distance. First of all any comments on this idea and also I am struggling to get the sample and hold gate to work. I'm using the 4066 IC and have connected this as said in the CMOS Cookbook but without success any ideas of how to get around this and whether my project is worthwhile?
Many Thanks :)
 
Why didn't you attach the schematics of the modulator, transmitter, receiver and demodulator?
