An apparatus and method therefor substantially reducing the interference of a harmonic frequency component (301) of a clock signal with a filtered received signal (302), comprises a frequency spreading signal generator (127) and a signal modulator (125). The frequency spreading signal generator (127) produces a frequency spreading signal (130). The signal modulator (125) modulates the clock signal, produced by a clock signal generator (129), with the frequency spreading signal (130) to produce a modulated clock signal (131) including a modulated harmonic frequency component (303). The power level of a modulated harmonic frequency component (303), corresponding to the harmonic frequency component interfering with the filtered signal (202-204), is spread over a frequency bandwidth (f6-f7) greater than the predetermined frequency bandwidth (f4-f5) causing the power level of the modulated harmonic frequency component (303) within the predetermined frequency bandwidth (f4-f5) to decrease.
