摘要：An improved digital frequency demodulator and method for demodulating asampled asynchronous FM input signal that determines the time duration of eachsuccessive half cycle by counting the number of successive samples of the same polarityand by interpolating between the samples immediately before and immediately after thedetected zero crossings at the beginning and the end of each half cycle.
