kaiser滤波：用kaiserord生成阶数，及beta值-filter using kaiser

这是四个用普通方法编写的FIR数字滤波器的程序和用kaiserord函数编写的，共8个-This is a common method used to prepare four FIR digital filter procedures and functions written by kaiserord of 8

设计一个高通最优FIR滤波器，过渡带为1000-1500Hz,采样频率为8000Hz,通带纹波最大为0.001.绘图比较系数12位、14位量化以及无量化时的幅度响应曲线(A high pass FIR filter is designed. The transition band is 1000-1500Hz, the sampling frequency is 8000Hz and the maximum ripple is 0.00
