IIR数字滤波器的设计，抽样频率为2*pi*1.5*10^4,通带截止频率为2*pi*1.5*10^3-IIR digital filter design, sampling frequency of 2* pi* 1.5* 10 ^ 4, pass-band cut-off frequency of 2* pi* 1.5* 10 ^ 3

A set of IIR filter design source code with GUI, this tool can design most of Doppler filter shapes, including classic 6dB, Flat, Rounded, Bell shape, Guassian shape, etc.
