Another example of a code-modulation system is delta modulation. As in PCM, the range of signal amplitudes is quantized, and binary pulses are produced at the sending end at regular intervals. However, in delta-modulation systems, instead of the absolute quantized signal amplitude being transmitted...

The meaning of PULSE CODE MODULATION is modulation of a radio wave or signal in which the intelligence is conveyed by a code or order of pulses of the wave that are usually all of the same size and shape and that are transmitted at multiples of a standar
抽样定理是任何模拟信号数字化的理论基础,PCM编码就是建立在抽样定理基础之上的,PCM编码主要包括抽样、量化、编码三个步骤。 (1)抽样:在满足抽样定理的条件下,每隔固定的时间间隔取出模拟信号的采样值,把连续时间的模拟信号转换成离散时间连续幅度的抽样信号。 (2)量化:将抽样取得的离散时间连续幅度的抽样信号转换成离...
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…
