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 ...
This paper presents the Adaptive Differential Pulse Code Modulation (ADPCM) method of digitally storing and reproducing speech or other waveforms. A detailed explanation of the encoding steps is given ...
Pulse code modulation for high quality sound distribution: Quantizing distortion at very low signals
In PCM systems, distortion of very low level signals is known to occur, and in high-quality programme distribution it is the most objectionable signal degradation caused by this kind of system. This ...
Maxim Integrated introduces two digital-input Class D power amplifiers that simplify designs, eliminate complicated programming, reduce noise, and hasten time to market. The MAX98355A (pulse-code ...
