The RANDOM VOLTAGE GENERATOR produces random voltages which vary smoothly or in a stepped manner. Random timing pulses are also available. Rate of change of all outputs is voltage controllable over a wide temporal range. PLEASE NOTE: The noise source and S/H source are built into the module and does not require the NOISE SOURCE module to function. White, Pink and the S/H source are available via the corresponding pads located on the back of the module. These pad can be broken out to external jacks to offer a full range noise source.
