  • System and method for reduced deviation time domain FM/PM discriminator to achieve a reduced bandwidth frequency or phase modulation communications channels
    Patent number: 7272368
    Abstract: The present disclosure provides a receiver for receiving a narrow frequency deviation frequency modulated or phase modulated base band signal including a mixer for mixing the received narrow frequency deviation signal to generate an intermediate frequency signal, a band pass filter for filtering the intermediate frequency signal, and a narrow band discriminator circuit that performs a time domain expansion of the modulation deviation of the intermediate frequency signal and discriminates the base band signal.

  • System and method for superheterodyne frequency multiplication signal expansion to achieve a reduced bandwidth frequency or phase modulation communciation channel
    Publication number: 20030095201
    Abstract: The present disclosure provides a method and apparatus for communicating a base band signal via a communication channel that connects a transmitter to a receiver comprising the steps of modulating the base band signal into a low frequency deviation modulated signal, transmitting the low frequency deviation modulated signal with a transmitter, receiving the low frequency deviation modulated signal with a receiver, mixing the received signal to an intermediate frequency signal, multiplying the intermediate frequency signal by to a multiplied frequency signal, multiplying a reference signal having a frequency generally equal to the center frequency of the intermediate frequency signal by a multiple that is one greater than or one less than the multiplied frequency signal to create a reference multiplied frequency signal, subtracting the reference multiplied frequency signal from the multiplied frequency signal to generate a wide band frequency signal, and discriminating the wide band frequency signal to obtain t
