PCM编码系统的设计【课程设计】PCM编码（又叫脉冲编码调制）：数字通信的编码方式之一。主要过程是将话音、图像等模拟信号每隔一定时间进行取样，使其离散化，同时将抽样值按分层单位四舍五人取整量化，同时将抽样值按一组二进制码来表示抽样脉冲的幅值。-PCM coding system design curriculum design】 【PCM encoding (also known as pulse code modulation): digital communications, one of the encoding. The main process is to voice, image and other analog signal at a certain time for sampling, to discretization, sampling at the same time, the value of homes by the hierarchical units in five four rounded to quantify the sampling values at the same time, a group of binary code to indicate the sample pulse amplitude.
