  • Radio interference detection device for use in a multi-channel access angle-modulation radio system
    Patent number: 4498195
    Abstract: A radio interference detection device for use in a multi-channel access angle-modulation radio system. A detecting system detects a received signal prior to angle demodulation and produces an AM component of the received signal which is then rectified. A determining section then determines the level of the rectified signal for use in detecting interference in accordance with a determination result. The determining section includes an angle demodulator for angle-demodulating the received signal, a first comparator for comparing the angle-demodulated signal and the rectified signal, a second comparator for producing the detection signal when the rectified signal exceeds a predetermined level and a gate for passing the output signal from the second comparator only when the angle-demodulated signal is smaller than the rectified signal.
