数字信号处理中特有的有限字长问题,包括量化误差的统计分析、量化误差通过LSI系统的行为、滤波器系数量化后对系统性能的影响、乘法运算中舍入误差在IIR系统和FIR系统中的表现等。通过这些讨论可得到一些有重要指导作用的结论,如信噪比和字长的基本关系,系统不同实现形式对舍入误差的敏感性等,这对我们设计和实现数字系统都是非常有用的。
再加一句话: 本课题的目的就是通过MATLAN来实现有限字长影响的统计分析,需要1、了解有限字长的相关知识;2、学会使用MATLAB软件;3、基于MATLAB实现有限字长影响的分析。
Say digital signal processing is to make use of computer or special use sells equipment at reduced prices simplely, the acquisition being in progress to the signal, exchanges , treating such as value of assessment and identification handles synthetically with the method that numerical value calculates,use it to achieve extract information and easy to apply purpose. System has digital signal processing nimble , accurate , anti-interference is strong , the equipment dimension is young , cost of construction low velocity, waits for outstanding merit quickly, these all are that are what analog signal treatment system has no way to comparison. Proper limited digital signal processing middle character strong point problem, statistic analysis , quantization error including quantization error pass an impact of systematic behavior of LSI , the wave filter modulus quantization queen over system function , roundoff error is in IIR system and behaviour in FIR system etc. in multiplication arith
