  • High speed squelch circuit
    Patent number: 4359780
    Abstract: A high frequency squelch circuit for communications receivers with relatively long time delay when operating on weak signals with a short time delay on strong signals which completely eliminates any audible noise burst, and with continuously variable delay as an inverse function of signal strength at intermediate signal levels. The high speed squelch performance is achieved without degrading chatter performance by operating at frequencies above the audio range and utilizing wider noise bandwidth.
