In a digital circuit in which electromagnetic interference is generated at the fundamental and harmonic frequencies of the digital circuit clock source, a clock source for reducing the peak spectral content of said interference. The clock source includes a noise source for generating a broad band frequency noise signal and a filter circuit for receiving and bandpass filtering the noise signal and providing the filtered noise signal as the clock signal.
