SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, AND PROGRAM

Abstract:

The present technology relates to a signal processing device, a signal processing method, and a program that make it possible to suppress deterioration in audio characteristics. The signal processing device includes: a low-pass filter that performs filter processing on a PDM signal; and a PWM conversion unit that performs PWM conversion on a multibit signal obtained by the filter processing and generates a PWM signal. The present technology can be applied to an audio reproduction system.
