I would like to build a circuit to digitize an audio signal, possibly in
PCM form, and record it on my VCR, and also to play it back.  The video
bandwidth should make it easy, but I don't know enough about video signals
and VCR's.  Does anyone know what I have to do to record a PCM signal on
a VCR?  Specifically, do I have to add a synch pulse in order to make it
record, or can I just take the PCM signal and put it on some carrier frequency
(channel 3, for instance) and feed that directly into the VCR without
simulating NTSC format?  Is there anything, besides the synch pulse, that
I have to do to the signal to make it record?

Thanks, in advance, for any help you may be able to offer.  Please email
your response to:  simmonds@demon.siemens.com

If I get any useful answers, I'll post a summary.
