ADC Technology - PCM/DPCM/ADPCM/DM/ADM

Analog to Digital Conversion: Technologies used to convert analog signal to digital signal PCM (Pulse Code Modulation) The most basic form of ADC. Simply, it takes four steps of Sampling - Quantization - Digitization - Encoding. Sampling: Takes samples of analog signal at regular interval. Quantization: Process that truncate each sampled value as the ones that computer can represent. Digitaizati..
