Abstract:
A method of processing a digital radio broadcast signal in a digital radio receiver includes: receiving baseband signal samples at a first sample rate; adjusting the sample rate of the baseband signals based on a difference between a receiver clock and a transmitter clock to produce adjusted baseband signal samples at a second sample rate; filtering the adjusted baseband signal samples to separate a digital component of the samples and an analog component of the samples, wherein the digital component and the analog component are synchronous; and separately demodulating the digital component and the analog component to produce a digital output signal and an analog output signal. A receiver that uses the method is also provided.
