PCM Transmitter

[chinsoon]

Hello there,

can anyone kindly provide me some circuit diagrams of PCM transmitter and receiver that are can be connected to the parallel ports of the computers...

I have tried to look for it but have came to a dead end.. so any help is very much appreciated.

thanks in advance

you cannot Txmit the pcm signal directly , you need to modulate (ref : Manchester encoding) , according to Nyquist criterion, and transmit . design each part separately , different ckts are available in the net for each part .
