Abstract
An electronic apparatus includes at least a receiver having a synthesizer section for selecting a receiving frequency and providing an information signal corresponding to the selected receiving frequency, a microcomputer operating on a clock signal for controlling the synthesizer section, and a circuit responsive to the information signal for shifting the clock frequency when the selected receiving frequency is a frequency disturbed by a higher harmonic of the clock frequency, thereby to avoid disturbance of reception of the broadcast signal without requiring undue reduction of the clock frequency.
