Abstract
A clock generator serves to generate a stable frequency system clock for a clock-controlled electronic device. To ensure that the system clock causes only little electromagnetic interference to nearby electronic equipment, the system clock is modulated with respect to a reference clock by means of a phase modulator controlled by a random signal source which is noise colored by means of a weighting device.
