Abstract

PURPOSE:To restrain distortion of the output signal, bygenerating a narrowwidth pulse synchronously with the pulse carrier signal and by adding this pulse to apply the result to anintergrating circuit and by changing inclination at the tip of the triangular wave signal of the output. CONSTITUTION:A pulse which has a width narrower than the pulse width of the pulse carrier signal from pulse generating circuit 1 is generated synchronously with this pulse carrier signal by the second pulse generating circuit 13. The addition result of both pulses is input to integrating circuit 12, and the triangular wave signal with inclination at the tip (near the maximum amplitude part) changed is obtained as the output. The signal from audio input terminal 3 is input to the intergrating circuit also and is compared with the triangular wave signal above, and a pulse wideth modulation signal with distortion restrained is obtained from comparator 8.
