摘要
主要研究了基于窗函数法设计FIR数字滤波器,介绍了不同窗函数的定义和特性,仿真分析了不同窗函数对FIR数字滤波器设计性能的影响,以及给出在实际工程设计中,如何选择合适的窗函数进行信号分析和处理。
This paper studies the design of FIR digital filter based on the window function method.This paper introduces the definition and characteristics of different window functions,analyzes the influence of different window functions on the performance of the FIR digital filter.Finally,it presents how to select the appropriate window function for signal analysis and processing in the practical engineering design.
