IIR 数字滤波器的设计与实现
设计一个巴特沃兹数字低通滤波器,其技术指标为:3dB带宽为0.2π,阻带截止频率为0.3π,通带纹波为1dB,阻带衰减大于30dB,采样间隔T=10ms。
1)采用冲激响应不变法;
2)采用双线性变换法设计;
3)采用FIR的窗函数(Hanning窗、Hamming窗或Blackman窗)设计。(A Butterworth digital low-pass filter is designed. Its technical specifications are: 3 dB bandwidth is 0.2 pi, stopband cut-off frequency is 0.3 pi, passband ripple is 1 dB, stopband attenuation is more than 30 dB, sampling interval T=10 Ms. 1) Impulse response invariance method is adopted. 2) Design by bilinear transformation method; 3) FIR window function (Hanning window, Hamming window or Blackman window) is used to design.)
