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 ...

The various methods for converting analogue signals into the form of pulse-code modulation and back again are reviewed. Reasons are given for preferring a particular method of conversion called ...

For technical and economic reasons, the present network of lines used for distributing sound signals to transmitters at audio frequencies will eventually have to be replaced by some telecommunication ...

Equipment is described which has been constructed for converting analogue television signals into 8-bit PCM signals and vice versa. The conversion rate used for video signals is approximately 13 ...

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 ...

Abstract: Speech coding is important for effective storage and transmission of audio signals. However, current Interactive Multimedia Association Adaptive Differential Pulse Code Modulation (IMA-ADPCM ...

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 ...

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 ...

One of the simplest ways to generate a DC analog voltage level from a microcontroller is by using its built-in pulse-width modulation (PWM) peripheral. This article describes the principle behind PWM ...
