Pulse density modulation (PDM) is a compact digital audio format used in devices like MEMS microphones and embedded systems. This compact primer eases you into the essentials of PDM audio. Let’s begin ...

Design considerations for pulse density modulation (PDM). Design considerations for inter-IC sound (I 2 S). Pros and cons of two popular digital interfaces in MEMS microphones. Small, portable ...

[esot.eric] was trying to drive a motor and naturally thought of using pulse width modulation (PWM) to control the motor speed. However, he found that even with a large capacitor, his underpowered ...

What is PDM and what is it doing in my microphone? PDM stands for Pulse Density Modulation. It's one of the formats in which you can waggle a two-level signal so that it has a probability k in one ...

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 ...

Cypress's Dave Van Ess proposes a novel way of analyzing mixed-signal circuits in terms of serializing the digitized analog signal and then assesing the relative time the signal is high. As an “old ...
