Analog transmission is not particularly efficient. When the signal-to-noise ratio of an analog signal deteriorates due to attenuation, amplifying the signal also amplifies noise. Digital signals are ...

New core enables hardware conversion of mono or stereo PDM streams to PCM, with configurable audio processing and flexible ...

The feasibility has been investigated of applying PCM to the distribution of stereophonic programmes of the highest broadcast quality in time-division multiplex. By this means all the programmes ...

The MAX98357A are digital pulse-code modulation (PCM) input Class D power amplifiers that provide Class AB audio performance with Class D efficiency. These ICs offer five selectable gain settings (3 ...

[esot.eric] was trying to drive a motor and naturally thought of using pulse width modulation (PWM) to control the motor speed. However, he found that even with a large capacitor, his underpowered ...

Raytheon Co., Tucson, Ariz., is being awarded an $8,761,875 modification to a previously awarded firm-fixed-price contract for the replacement of the Pulse Code Modulation (PCM) Encoder due to ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...

Ever notice that the ESP32-S3 doesn’t have a digital-to-analog converter? [Chris] did and asserts that he doesn’t care because he can just use the PDM system to get the same result. PDM — pulse ...
