In MIPI Soundwire: Digital Audio Simplified, we mentioned that digital audio formats including Pulse Code Modulation (PCM) and Pulse Density Modulation (PDM) are target applications for MIPI Soundwire ...

Done right, digital audio is flexible, robust, and of very high quality. Pulse code modulation (PCM) recording, lossless surround formats, and even lossy compression (at least at high data rates ...

Technically, cellphones compress the sound of a person speaking so it seems like synthetic speech.

So instead of PWM he decided to experiment with pulse density modulation. The idea is to use smaller pulses over a longer period of time and make the average power equal to the percentage motor ...
