摘要
在DSP系统中,由于有限字长效应的存在导致了影响系统性能的误差.以IIR型数字滤波器为例,对实际DSP系统由于量化等过程而出现的有限字长误差进行了分析,并提出了使这种误差最小化的方法.
The use of finite wordlengths introduces errors that can affect the performance of DSP systems. Taking an IIR digital filter as the main vehicle, the errors that arise in practical DSP systems due to quantization are analyzed in this paper. Techniques for eliminating or minimizing them have been presented.
