脉冲编码调制是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入取整量化，同时将抽样值按一组二进制码来表示抽样脉冲的幅值。(PCM pulse code modulation is one of the encoding methods of digital communication. The main process is to voice, image and other analog signal at a certain time for sampling, the discretization, while the sampling values by the hierarchical units four to five homes in rounding quantization, while the sampling value indicates the sample pulse amplitude according to a set of binary code.)

数值微分精度及步长的关系，截断误差和舍入误差，体会误差对结果的影响，用算法1 和算法2 分别得到的结果进行比较，由Taylor公式可得到两种算法的截断误差(Accuracy of numerical differentiation and the relationship between step length, truncation error and rounding error, the error on the results of experience with algorithm 1 and algorithm 2 respectively, to compare the results obtained by the Taylor formula for the truncation error of two algorithms available)
