ABSTRACT:
A radio receiver includes a processing unit that may generate a respective phase value corresponding to each of a plurality of digital samples of a received complex frequency modulation (FM) signal. The receiver also includes an impulse unit that may detect whether a linear combination of a phase value of a current sample and a phase value of one or more previous samples will produce an impulse at an output of an FM demodulator. If the impulse unit detects that an impulse will be produced at the output, the impulse unit may replace the output of the FM discriminator with a predetermined value.
