With the aid of CCS software,the FIR filter is designed by the rectangular window function. The design of the FIR filter mainly contains of the input sequence x（ n） design,the unit impulse response h（ n） design and the linear convolution program design. Firstly by designing the input sequence x（ n） and the unit impulse response h（ n）,the values of the input sequence x（ n） and the unit impulse response h（ n） are calculated; Secondly the linear convolution of the input sequence x（ n） and the unit impulse response x（ n） is calculated by using the linear convolution program,and the output sequence y（ n） of the FIR filter is obtained. The time domain waveform and the spectrum of the output sequence y（ n） is observed by the time / frequency menu.
