About: Zero crossing detector   Sponge Permalink

An Entity of Type : owl:Thing, within Data Space : 134.155.108.49:8890 associated with source dataset(s)

A circuit which produces a trigger output whenever an input signal crosses the zero-volt axis. By counting the zero crossings in a given period of time, a system can use the detector to perform a pitch conversion function, assuming that the input signal is regular and not too complicated in shape. Zero crossing detectors are most commonly used in auto tune circuits to detect the frequency of the VCO being tuned.
