1. A method for demodulating a radio frequency (RF) signal, the method comprising:
determining a nearest harmonic of a clock signal from a central frequency of a received frequency band; and
when the nearest harmonic is in the received frequency band, setting an intermediate frequency of a Near Zero Intermediate Frequency (NZIF) receiver to a difference between the central frequency and the nearest harmonic.
