Pulse Code Modulation - Modulation, Types, Advantages and …

Some forms of PCM combine signal processing with coding. Older versions of these systems applied the processing in the analog domain as part of the analog-to-digital process; newer implementations do so in the digital domain. These simple techniques have been largely rendered obsolete by modern transform-based audio compression techniques, such as modified discrete cosine transform (MDCT) coding. Web- Pulse Code Modulation (PCM): 1- Sampling (PAM). 2- Quantization. 3- Binary encoding. 4- Line or block coding. 1. Sampling (PAM) The first step in PCM is sampling. The analog signal is sampled at equal interval, every Ts s (sample interval) The inverse of sampling interval is sampling rate or sampling frequency. lista hsk 100
