[masterleous]

Hello Guys,
My project is Voice & Data Multiplexing using TDM ,
I found a Circuit Diagram of the above project, the circuit is for Analog TDM using Analog MUX CD14051, I want to obtain Voice from SoundCard of my computer and also Data from Parallal/Serial PORTs, but my concern is to get analog Data as the MUX is analog, the question is that.
Can i obtain Analog data from any Computer port ?
If yes than How............

masterleous,
Your computer port will send digital data only. Your sound card will send analog data to the speakers. Perhaps if you could post the circuit that you have found others will be able to help.
