ABSTRACT:
Method and apparatus for recovering a message signal from a carrier signal. More specifically, method and apparatus for demodulating a frequency modulated signal using measured time intervals between zero-crossings of a received carrier signal. The method and apparatus employing averaging techniques to provide a more accurate signal representing the message signal. The method and apparatus employing mapping techniques to provide a more accurate signal representing the message signal.
