Abstract
A radio frequency (RF) receiver includes an intermediate frequency (IF) mixer that generates an output signal based on mixing a hybrid in-band, on-channel (IBOC) signal with an intermediate frequency signal. An oscillator generates the intermediate frequency signal; wherein the intermediate frequency is less than a bandwidth of the IBOC signal.
