Abstract

PURPOSE:To reduce amplitude and phase distortion of a voice signal by performing pulse width modulation with regard to a distributed signaland the voice signal which are out of phase with each other, by synthesizing them after passing them through low-pass filters, and then by generating an amplitude modulated wave by mixing output signals of the low-pass filters with a high frequency signal. CONSTITUTION:The output signal of an oscillator 21 is supplied to an opposite phase distributor 22. Output signals made opposite in phase are supplied to pulse width modulators 23 and 24 together with a voice signal fA. Modulation output signals are supplied to LPFs 25 and 26 to eliminate high frequency components. The output of an oscillator 27 is divided equally by distributor 28, whose outputs are supplied to power amplifiers 29 and 30. The amplifiers 29 and 30 mix the output signals of the LPFs 25 and 26 with the high frequency signal of the distributor 28 to generate an amplitude-modulated wave, which is outputted to a synthesizer 31.
