The
Sample & Hold used in the ASM-2 is based on a fairly straight-forward
and common design that uses an FET to store the `sampled' voltage
on to a low-leakage capacitor.
The S&H sample
clock may be derived from an external source or taken from the S&H
low-frequency oscillator dedicated to the S&H module.
The S&H LFO has a frequency range of <0.5Hz to >650Hz.The S&H will
accept an input signal up to +/-10V.
An LED is included
on the board to provide a visual status of the S&H trigger signal.
