摘要
在采样时由于量化、舍入或噪声的影响,得到的实际采样值与真实值有偏差。为了控制信号的失真度,误差研究尤显得十分重要。本文将给出截断误差、振幅误差的上界估计,并对多种因素形成的综合误差进行研究,给出相应的结果。
For the effect of quantification?round-off?and noise, there are errors between the sampling and real data. In order to control the distortion degree, error analysis is very important .In this paper we obtained the upper bound of block error, amplitude error and studied the synthesis error.
