208 Comparator & Rectifiers - 4HP

A Comparator is an electronic circuit that compares two voltages and switches its output to indicate which is larger. The Comparator operates between -10 or +10V. The Output is always -10V if below Threshold and +10V if above Threshold.

A Rectifier is an electronic circuit that is used to transform AC signals to an equivalent DC signal while removing one of it’s polarities, i.e. Positive rectification excludes negative signals and vice-versa.
Both sections can be used to change the shape of any waveform as well as its harmonic content.


  • 4HP totally analog module.
  • Comparator with Threshold Knob
  • 4 Precision Rectificated Outputs::
  • Positive Half Rectification
  • Positive Full Rectification
  • Negative Half Rectification
  • Negative Full Rectification
  • Comparator can be used with VCO’s to create a Square Wave with PWM control
  • Comparator can also be used with complex audio signals for a “Fuzz” effect.
  • Full Rectification can be used to double a VCO frequency.
