Abstract: In one embodiment, an apparatus includes a first receiver path with a first digitizer to digitize an incoming signal obtained from a radio frequency signal including at least a first desired channel into samples, the first digitizer to operate at a first sampling frequency, a first sample rate converter coupled to an output of the first digitizer to receive the samples at the first sampling frequency and to output the samples at a fixed sampling frequency, and a first digital processor to receive and process the samples at the fixed sampling frequency. The apparatus may further include a controller to receive a frequency change indication and to dynamically control the first sample rate converter to accommodate a change in the first sampling frequency from a first rate to a second rate.
