NSH stands for Noise, Sample & Hold – a module which features analogue Noise and a pair of Sample & Hold processors.
The Sample & Hold circuits are identical, each with Input, Output & Clock input (with internal comparator, trigger level c.+1V). The Source Input can be set to either an external signal or takes the White Noise source direct. The S&H can be run at audio rates for ‘bug-crushing’ (analogue sample-rate reduction – NOT bit-crushing).
The Noise section is standard transistor-based White Noise, with a second Filtered output which passes through a simple tilt filter around 1kHz cutoff.
Current: +ve 25mA, -ve 20mA
