Definition: A technique by whichanalog signal gets converted into digital formin order to have signal transmission through a digital network is known as Pulse Code Modulation. It is abbreviated asPCM. PCM systems are basically signal coders also known aswaveform coders. PCM allows the representation...

PCM(Pulse Code Modulation)脉冲编码调制,是将连续的模拟信号变换成离散的数字信号的过程,是模数转换的实例化,步骤包括采样、量化、编码。在调制过程中将模拟信号每隔一定时间进行采样,使其离散化,同时将采样值按分层单位四舍五入取整量化,同时将采样值按一组二进制码来表示采样脉冲的幅值。 1、采样—通常为8000Hz:...
Linear pulse code modulation (LPCM) is a method for digitally encoding uncompressed audio information, where audio waveforms are represented by a sequence of amplitude values from a sample on a linear scale in which the values are proportional to the amplitudes, as opposed to being the log of ...

Pulse-code modulation (PCM) requires a large bandwidth because of the large number of pulses that must be transmitted. Optical pulses have the necessary bandwidths at the frequencies required. PCM as a data quantization and formatting technique is misnamed as such. The modulating function, i.e....
