ABSTRACT:
A method and device for digitally demodulating a frequency modulated signal includes: calculating a phase of a digital complex baseband signal of a received frequency modulated signal, calculating an unwrapped phase of the calculated phase, detecting and eliminating 2.pi. phase jumps in the unwrapped phase to generate a corrected phase, and differentiating the corrected phase.
