quad comparator
The QCOMP board consists of four independent functions, which are useful in the production of square waves and variable pulse waves.
The Comparator reference level can be a time-varying control voltage, a complex audio signal, or a fixed preset voltage.
Additionally, the comparators are useful for level detection and for logic decisions based on amplitude.
The QCOMP board is a revisited, quad version of a well known circuit.
