Model 232

Frequency Detector

The Model 232 Frequency Detector is a combination of circuits used to generate a CV and sine wave output that track an incoming signal over a frequency range of 80 Hz to 2500 Hz; including a frequency detector, envelope follower, phase locked loop, automatic gain control, gate/trigger extractor, and pitch-to-CV convertor. This would allow the module to track the input of an acoustic instrument as both a sound source and a CV source.
