  • Adjacent channel rejector
    Patent number: 3953802
    Abstract: An adjacent channel rejector for use in communication systems such as TACAN includes a high gain amplifier adapted to be driven into saturation in response to signals in the channel, a wide band filter/demodulator connected to the high gain amplifier and a narrow band filter/demodulator connected to the amplifier. The rejector further includes an amplitude comparator coupled to these filters/demodulators for determining when a desired signal is in the channel thereby providing adjacent channel rejection.
