Q130 Rectifier/Clipper
Aug 2014
The Q130 Module provides both a signal rectifier and a voltage controlled clipper.
These functions have the effect of changing a waveform and its harmonic content or
simply changing a control signal for use by another module.
The Clipper section of the module is used to clip off the top, bottom, or both of a
waveform. The level at which the clip occurs can be set manually with the front panel
control knob or set with a voltage control signal from another module. The amount of
effect that the voltage control signal has can also be adjusted.
The Rectifier section simply takes an input and rectifies it. This has the effect of dou-
bling the frequency of a sine wave, while turning a sawtooth wave into a triangle
wave with the same frequency. Both positive and negative sides are available simul-
taneously.
Patch the two sections together to create completely new types of waveforms.
