Introduction
The ID2510 is a versatile noise producing module, using analog noise as the basic source. Digital noise is produced
by sampling the analog noise with a window comparator and a sample and hold circuit. The sample trip point and
window width are both voltage controlled.
The ID has a built in 12dB voltage controlled filter with low pass and band pass functions that processes a mix of
analog and digital noise.
A second sample and hold circuit samples the filter output for random stepped voltage outputs. A built in voltage
controlled clock or an external clock can be used to step the samples.
The ID also features a digital S/H and quantizer circuit that produces chromatic scale outputs at 1V/octave. A
trimmer on the PCB also allows the quantizer to be tuned to a major, minor or diminished scale.
Separate outputs are provided for filtered noise mix, analog noise, digital noise, S&H and quantizer.
