UBZR1 Noise Generator

Summary/Usage

Functional Description

The noise module uses a transistor operated in reverse mode above breakdown voltage with current limited.

The following opamp circuits filter for white noise (cutting non-audible high frequency), pink noise with a spectrum d p / d ln f = constant and "red" noise with still more emphasis on low frequencies.

Final amplification is done with an LM 13700 which serves as a built-in VCA and provides for two separate current outputs.
