The AM demodulator generally uses an envelope detector composed of analog components,and is therefore unstable and difficult to implement.This paper uses the digital Hilbert filter to realize a digital envelope detector based on the principle of the equivalent lowpass representation of the bandpass signals,and implements soft debugging in CCS.In the course of the implementation,LinkforCCS and DSPLIB are utilized not only to reduce the time of development but also to improve the efficiency of the algorithm.
