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 Width Modulation (PWM) is a fundamental technique in power electronics that facilitates the efficient control of power delivery by modulating the width of voltage or current pulses. This method ...
