NS-4 Noise and S&H

Analog noise generator and sample/hold

The NS-4 is a true analogue noise generator with four noise/random signal outputs; sample and hold (s/h), white, pink and red.

The S/H generates a random signal controlled by two voltage controlled parameters; rate and lag (slew rate). Rate controls the period for every sample point from 10 seconds (0.1 Hz) to 2 millisecond (500 Hz). Lag controls the slew rate of the incoming S/H signal from 0.1 Hz to 1000 Hz. The outgoing signal is, in other words, filtered by a voltage controlled low pass filter with 12 db/octave slope. The S/H rate and the S/H lag can be controlled manually by knobs and by external signals (Rate CV and Lag CV). The rate generator can be synced to an external signal with any shape (S/H trig input). The S/H can also sample an external signal (ext S/H) instead of using the internal noise generator. The level of incoming signal can be controlled manually (ext S/H level).

White noise:
White noise is a full audio bandwidth noise generator.

Pink noise:
Pink noise is a filtered white noise generator by 3db/octave across the whole audio frequency range.

Red noise:
Red noise is hard filtered and contains essentially only frequencies up to 200 Hz.
