A digital demodulator that may be utilized in integrated radio receivers and/or
integrated radios includes a mixing section, 1st and 2nd digital
comb filters, phase locked loop module, and a data recovery module. The mixing
section is operably coupled to produce a digital I signal and a digital Q signal
from a digital intermediate frequency signal. The 1st comb filter filters
the digital I signal while the 2nd comb filter filters the digital Q
signal. The phase locked loop module produces a digital signal from the filtered
I and filtered Q signals. The data recovery module interprets the digital signal
to recapture a data stream.
