System and method for reduced deviation time domain FM/PM discriminator to achieve a reduced bandwidth frequency or phase modulation communications channels |
摘要 |
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.
