Abstract
The electronic device and a corresponding signal processing method disclosed herein reduces electromagnetic noise. To that end, the electronic device includes a delay line, an oscillator, and a modulator. The delay line generates a spread spectrum clock signal from an input clock signal, where a timing jitter and a period of jitter of the spread spectrum clock signal are controlled at each period of the spread spectrum clock signal based on a digital code. The oscillator uses the spread spectrum clock signal to generate a processing signal. The modulator modulates the processing signal as a function of an audio signal.
