    Hi to ALL
    i wonna connect 8 mics to ADC0808, and multiplex signals, then after multiplexing, i want to transmit the multiplexes signal to computer...
    i have completed idea in my mind, but still confuse to make circuit
    so any can anyone of u will do give me favor to complete this task!!!
    the task is
    1)1st connect 8 sound sources(MICROPHONE) to ADC0808....(i need circuit for this)
    2)2nd is MULTIPLEXING
    3) after multiplexing, how did i transmit signal to COMPUTER??? and what do i did for connection with PARALLEL port!!!

    I suggest you get the data sheet for the converter - http://www.national.com/mpf/DC/ADC0808.html

    It has all the information you need. With only 8 bits resolution and slow switching between channels, you will get low-quality sound conversion.
