Hi all
I would like to design an analog 8 audio channels multiplexer ( 8 to 1 ), and I have a couple of questions please. I'm wondered if anybody cna help me.
The audio bandwidth of each channel should be from 10Hz to 25 kHz.
In what manner do I have to calculate the MUX ( clock ) fequency please ?
Is it correct:
fmux = fmax channel * 2 * channel number ?
( moltiplication by 2 is for Nyquist )
On my case:
fmux = 25kHz * 8 * 2 = 400 kHz ?
Or can I just consider 25kHz * 8 = 200 kHz ?
How can I sincronize Muplitplexer with the demultiplexer in order to extract each single ghannel please ? ( 1 to 8 )
Thank you very much for your help
