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.

In summary, pulse code modulation involves sampling the analog signal, quantizing the value of the sample, and creating a fixed bit length digital word for each digitized sample.

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 ...

Those following the ProtoStack tutorials will be happy to hear that there is a new installment which explains Pulse Width Modulation. If you’ve never heard of PWM before, it’s a method … ...

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 ...

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 ...

The most common audio formats are PCM (Pulse Code Modulation) and Bitstream. Both these formats transmit a digital audio signal to your soundbar, but they work in different ways.

In response to the limitations of analog transmission, the carriers migrated to digital transmission using pulse code modulation (PCM) or adaptive differential pulse code modulation (ADPCM).

According to Pulse Code, "Modular looks, acts, and sounds like a hardware modular synthesizer to give you features that musicians want such as pulse width modulation, oscillator sync, 4 pole ladder ...
