PDM — pulse density modulation — is similar to PWM and ... PWM was one choice, and some example code uses a timer to do PDM. However, that is not very efficient. The other alternative is ...

Pulse-Code Modulation The growth of communications traffic has enhanced the attractiveness of this method, which converts messages into binary digits that can then be transmitted in the form of ...

Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation.

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 ...

Other systems use differences in time. For example, using pulse code modulation, pulses from different signals are interleaved in time, and by synchronizing the receiver and transmitter to look at the ...

The AR36T01 is a soft macro low-power digital microphone interface modulator IP. The IP converts stereo/mono 1-bit pulse-density modulated (PDM) bit stream data from external digital microphones ...

I talked about the digital-switching infrastructure called pulse code modulation (PCM), which was rolled out starting in the 1960s. But there’s another factor I didn’t discuss: Digital ...

The three lossless audio formats associated with Blu-ray players’ high-resolution audio soundtracks are Dolby TrueHD, DTS-HD Master Audio (MA) and Linear PCM (Linear Pulse-Code Modulation). These ...
