在FIR滤波器中用Kaiser窗函数，给出了低通、带通和带阻用Kaiser窗函数的FIR滤波器设计程序。-FIR filter used in the Kaiser window function, given the low-pass, band pass and band stop using Kaiser window FIR filter design program.

针对一个混和正弦波信号，设计FIR滤波器，给出了三种设计方法：凯塞窗函数设计带通滤波器法、FDATool设计法实现凯塞窗函数滤波器的低通、带通和高通三种滤波效果以及椭圆低通滤波器的设计法。利用matlab软件实现。-Sine wave for a mixed signal design FIR filter, gives the three design methods: Kaiser window function design band-pass filter method, the FDA

利用Kaiser窗函数，设计具有如下指标的FIR低通滤波器：fs=20KHz, fpass=4kHz, fstop= 5KHz, Apass=0.1dB, Astop=80dB。(The FIR low-pass filter designed by Kaiser window function is used for digital filtering.)
