An all digital signal detecting system using C8051F060 as its core was completed. It can maintain the phase relation of sampling signal and modulatingsignal.
Frequency modulation(FM): the form of modulation in which the frequency of the carrier is varied in accordance with the instantaneous value of the modulatingsignal.
