FIR滤波器的DSP实现
The Realization of FIR Filter on DSP
摘要
Abstract
The architecture of FIR filter and its design method were introduced.With an example the filter digital indexes were given and FIR filter tap coefficients were obtained by FDATool.Based on DSP,the signal being filtered produced by MATLAB was imported into a low pass FIR filter which was implemented by using C language and simulated by CCS.Compared with theoretical value, the simulation results are met, and the design of the system is correct and stable.According to their applications, FIR filters with different performance are usually realized.In their designs different FIR filter can be achieved by changing the tap coefficients.关键词
