This paper introduces the PDM modulation technology which is widely used in digital system nowadays. Result of the simulation proves that the ripple in analog signal has been attenuated, and relative to D/A conversion after PWM modulation.Hence, the PDM technology is more suitable for D/A conversion in low distortion digital system.
