An electronic system includes at least one element which is operative in response to clock signal pulses, of less than a maximum frequency of occurrence, from a clock signal source. A dither means is connected to the clock signal source for causing the frequency of occurrence to be varied such that electromagnetic radiation which accompanies the normal operation of the system is of a lesser interference effect than if the frequency of occurrence were substantially monotonous.
