Thaks again Raimund - I have an annoying habit of asking questions until I
really understand something -
are you saying that there is no advantage to having 4 samples representing =
a
waveform rather than say 2 samples ? Does this mean 2 samples is sufficient=
to accurately record a waveform ?

I understand, this wouldn't be the problem here.

of course also provide more temporal details on the waveform.
