PDM — pulse density modulation — is similar to PWM and, like PWM, requires a filter that could range from a simple RC network to an active filter. You can see the result in the video below.
With the rapid development of digital communication technology, pulse code modulation (PCM), as a basic digital signal processing technology, has been widely used in the fields of speech, image and ...
Pulse Width Modulation is a topic that tends to give a lot of beginners trouble. [Daqq], whose nixie plasma ball we covered a few days ago, has a simple but effective PWM project that you should ta… ...
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 ...

The "pulse code" in PCM comes from the telephone company's method of sending a pulse or no pulse down the line. Mu-Law signals typically ride on a single 64 Kbps DS0 channel in a T1 line.
When I wrote about why we should blame our hatred of phone calls on equipment and infrastructure rather than human habits, I talked about the digital-switching infrastructure called pulse code ...
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 ...
