Abstract

PURPOSE: To reduce the amount of hardware by providing a modulating means to which the audio sound signal outputted from an audio sound signal oscillating means and the sine wave from a modulating signal oscillating means are inputted, and modulating the audio sound signal by the sine wave.
CONSTITUTION: A modulating signal oscillating circuit 2 outputs 16Hz amplitude modulating frequency fc, and an audio sound signal oscillating circuit 4 outputs 400Hz sine wave frequency fo. A modulating signal y (n) having the amplitude modulating frequency fc and the audio sound signal having the sine wave frequency fo are inputted to a modulating circuit 3. The modulating circuit 3 subjects the audio sound signal having the frequency fo to amplitude modulation by the modulating signal y (n) to output a ringing tone signal. Thus, the capacity of a ROM is reduced though the ROM is used.
