本matlab函数，实现凯泽窗设计低通、带通、高通滤波器，综合在一个图显示。设计滤波器时，用到的脉冲函数和脉冲响应函数都在压缩包里，所用的频率是数字频率值。-The matlab function, designed to achieve Kaiser window low-pass, band-pass, high pass filter, integrated in a map display. Filter design, the use of the pulse function and impulse response function in the compression bag, the frequency used by digital frequency value.
