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!!!

waiting for GOOD RESPONCE

TAYYAB
 
Why not use a modern device?, a great many PIC's already have internal A2D and multiplexers, and can connect to the PC via parallel, serial, or USB (for selected 18F series devices).

here i give BLOCK DIAGRAM
i need about the circuitry of componont(OVERVIEW)

SIR first of all i m not know about that HOW TO PROGRAM PIC
2nd problem is the availiblity of these part over here in PAKISTAN
so i prefer ADC 0808

if u have some complete soultion about the PIC(CIRCUITRY, PROGRAMMING etc) then told me, i should do that

Presumably even Pakistan has some relatively modern components available?. Surely all micro-controller manufacturers now provide suitable devices with internal A2D and multiplexers - some PIC ones go back to the last century.

My tutorials show most of it, but not your specific requirement.
