Title: Pcm-pwm system amplifier
Inventor: OOSHITA AKIHIRO
IPC: G11B20/10
Filed: 1980-02-28
Abstract: PURPOSE: To improve the distortion of a PCM-PWM converter, by incorporating a circuit that detects the distortion of a PCM-PWM converter and a circuit that compensates the distortion component into a PCM-PWM system amplifier.  
     CONSTITUTION: The PCM signal A is converted into the PWM signal B through the PCM-PWM converter 2. If a distortion is caused in the conversion, the PCM code row of the PCM signal C obtained from the A-D converter 4 becomes different from the PCM signal A. Thus the error signal D obtained from the comparator 5 is obtained as an error code corresponding to the PCM signal C. The error code is applied as a high-level pulse when the signal C is smaller than the signal A. Then the adder/subtractor 6 performs an addition to obtain the corrected PCM signal E. As a result, the PWM signal delivered from the PCM-PWM converter 9 has a correct pulse duration.
