Abstract
A receiver squelch circuit has a programmable DC threshold level. The squelch circuit includes input circuitry that responds to an incoming signal by generating a decision signal when the DC voltage level of the incoming signal crosses a predetermined threshold level. A programmable control network selectively varies the predetermined threshold level.
