Abstract
A vehicular electronic apparatus contains a microcomputer, and a crystal oscillator for determining an operating frequency for the microcomputer. An oscillation frequency of the crystal oscillator is selected such that a frequency difference between a frequency of a broadcast wave received by a vehicular receiver and an oscillation frequency of the crystal oscillator or a higher harmonic of the oscillation frequency is 15 kHz or higher or 400 Hz or lower, to suppress an interference in receiving the broadcast wave.
