The Triple Comparator and Schmitt Trigger consists of three 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 module also contains a single, non-adjustable, Schmitt trigger. The output of the Schmitt trigger will rise to about 5 volts when the input falls below approximately 0.6 volts and will fall to approximately 0 volts when the input rises over approximately 4.3 volts.
