Abstract
Digital FM demodulator and method in which zero-crossings of a frequency modulated input signal are detected, a binary pulse is provided for each of the zero-crossings, and the binary pulse stream is filtered digitally to provide enhanced resolution of the incremental phase (frequency) of the input signal over a period which is asynchronous with the input signal. In the disclosed embodiments, the digital filtering is done with comb decimation filters, with a higher order filter being employed where greater resolution is desired.
