Using analytic PCM-to-PWM mapping, combined with a novel method for eliminating PWM-induced distortions (Jithering), a distortion-free, all-digital and high-quality PWM coder was developed. High efficiency and performance is achieved at switching frequencies between 44.1-176.4kHz. A Field Programmable Gate Array - based environment was used for the implementation of the PWM converter, which is suitable for any digital audio applications.
