A Bluetooth pulse code modulation (PCM) lookback test primarily verifies the functionality of the Bluetooth chip’s PCM ...

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 ...

Pulse-code modulation for high-quality sound-signal distribution: Appraisal of system requirements.

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 closely spaced ...

Oki Electric Industry today announced the development of three new models of Pulse Code Modulation (PCM) sound generator LSIs for mobile phones. The new products, the ML2863, ML2873 and ML2865 ...

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 ...

Pulse amplitude modulation (PAM) is already a widely adopted technology in high-speed digital communications. But to understand why it has become ubiquitous in serial data standards, you first must ...

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.
