  • Transceiver having improved voice actuated carrier and echo suppression circuit
    Patent number: 3942116
    Abstract: A transceiver comprising a transmit circuit for receiving a transmit audio frequency signal from a voice input transducer and including a delay line for delaying the transmit audio frequency signal, a modulator for converting the delayed transmit audio frequency signal to a transmitable radio frequency signal and a first switchable attenuator responsive to a control signal and operative to selectively couple the radio frequency signal to an output terminal for transmission; a receive circuit for receiving a responsive radio frequency transmission and including a demodulator for converting the received radio frequency signal to a received audio frequency signal, and a second switchable attenuator responsive to the control signal and operative to selectively couple the received audio frequency signal to a voice output transducer; and a control circuit including a transmit detector for detecting the transmit audio frequency signal level, a receive detector for detecting the received audio frequency signal level,
