Hmm-m-m...
That's an interesting thought! Presumably, we could use a system whereby
a short burst of a given tone represented a '1' and no signal (or perhaps
a different frequency, like RTTY?) a '0' signal. Then, the question would be
the minimum length of signal needed to identify it? (aka baud rate?).
Given that we can use 56K (bits, not bytes) modems...could this be
recorded on a shellac disc, given the inherent signal-to-noise ratio?
It could probably be done on vinyl...but are there any lifespan
considerations for vinyl discs?
