Re: Please explain white noise & random

2005-10-12 by selfoscillate

hello richard,

it doesn't make a difference which signal is presented
to the s&h input, you can use any signal.
the result is always a constant voltage at the s&h output,
no matter what signal is used as input.
the s&h doesn't track frequencies, so it is no
pitch-to-voltage converter. it simply samples the actual
input and outputs that value until the next trigger happens.
a pitch-to-voltage converter is something completely different.

best wishes
