Dual Comparator

Dual Comparator

Dual Comparator (COM)
The DUAL COMPARATOR (COM) provides several often useful house-keeping functions within the Serge system:

Logical Decisions: If the + input is greater than the - input, then the output will be high. If not, then the output will be low. 
Level Detection. A pulse will be generated whenever an input voltage reaches a pre-set threshold. For example, when an envelope detector reaches a certain loudness level, it can be used with the Comparator to generate a pulse to activate or de-activate other events programmed within the synthesizer. 
Voltage variable pulse width modulation of any of the Serge oscillators. 
“Squaring” audio signals, whereby frequency related pulses are derived from an input signal. These pulses can be used for frequency sub-division (via a Dual Slope Generator or Sequencer), or as raw audio, rich in harmonic content. 

In addition to the +/- inputs, each of the Comparators include a front-panel knob to manually set a threshold.
