PCM系统比脉冲仿照调制方法要杂乱一些,基带信息需要通过多次管理。在发射机中,这些管理进程主要是取样、量化、编码。量化和编码操作通常在一个电路中结束。在PCM系统的接收机中,这些管理是受损信号的再生、解码和量化样值序列的解调。当然,在传输线路上基于需要也进行信号的再生,这便是再生中继器

(The PCM system is a bit more complex than the pulse imitation modulation method, and the baseband information needs to be managed many times. In the transmitter, these management processes are mainly sampling, quantization, and encoding. The quantization and encoding operations usually end up in one circuit. In a receiver of a PCM system, these managements are regeneration of the damaged signal, decoding and demodulation of the sequence of quantized samples. Of course, the regeneration of the signal is also performed on the transmission line based on needs, which is the regeneration repeater)
