Abstract

The invention refers to an electronic digital system for transforming digital data of a Pulse Code Modulation, PCM, which constitute the usual form of data in several digital sound devices and systems (Compact DIsc, Digital Audio Tape and others), into a pulse series signal with Pulse Width Modulation, PWM and for reducing the non-linear and other distortions appearing during this transformation. It concerns an autonomous system which, either operates independently, or is combined with other stages of a digital sound amplifier or a digital to analog converter and which interferes in the sound reproduction chain as illustrated in fingures 2a, b, c between the digital sound source and the next stages which either are the Digital to Analog Converter, DAC), or the principal amplification stage (PCM amplifier). This system implements a transformation tof the PCM encoded stereo digital sound data, to an 1-bit pulse series with Uniform-sampled, Double-sided Pulse Width Modulation), with simultaneous suppression of the non-linear and other distortions that are known to be created suring the transformation of data from PCM to PWM.
