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.

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… ...

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 ...

Pulse Width Modulation (PWM) is a fundamental technique in power electronics that facilitates the efficient control of power delivery by modulating the width of voltage or current pulses. This ...
