  • Frequency estimation immune to FM clicks
    Patent number: 8185079
    Abstract: An apparatus for reducing audio clicks in frequency modulated radio system includes a receiver for receiving a frequency modulated (FM) signal, and a processor for demodulating the received signal and estimating a frequency error, wherein the processor is configured to determine phase variations of the received FM signal by comparing a phase of a first signal sample to a phase of a second signal sample, wherein the first signal sample and the second signal sample are separated in time by more than one sample.
    Type: Grant
