Description: 用双线性变换法设计IIR数字滤波器
滤波就是将外界干扰的不需要的频率滤除掉,一面影响要测试数据的结果。比如如果是心电波的话,如果这是外界有很大的噪声干扰,滤波就是把不必要的信号给抑制掉,以便对心跳的正常测试。通过图比较,滤波后的明显比之前的要平滑,就是滤去干扰噪声的结果。采样间隔对实验有影响,取的过大会导致频率混叠。-Bilinear transformation method using digital filter IIR filter design is to outside interference filter out unwanted frequencies, while the impact to test data results. For example, if it is so heart waves, if this is a great noise outside interference, filtering is unnecessary signal out to the curb in order to test the normal heartbeat. Through chart comparison, after filtering than before to smooth the noise interference is the result of least squares. Sampling interval of the experiment affect take-off frequency of the General Assembly leading to aliasing.

Description: 使用matlab实现设计IIR滤波器:冲激不变法、双线性变换法
设计一个巴特沃思低通滤波器,其技术指标为:3dB带宽为,阻带截止频率为,阻带衰减大于30dB,采样间隔T=10us。
1)用冲激响应不变法
2)用双线性变换法设计
3)用FIR的矩形窗函数设计
二、用双线性变换法分别设计低通、高通、带通、带阻四种滤波器。模拟滤波器带原型分别为切比雪夫滤波器和椭圆滤波器,采样率Fs=20kHz,指标如下:
1)低通:通带0~4 kHz,阻带5 kHz,通带衰减Rp=0.5dB,阻带衰减As=10dB。
2)高通:阻带0~4 kHz,通带5 kHz,通带衰减Rp=0.5dB,阻带衰减As=10dB。
3)带通:通带2kHz~4 kHz,阻带0~1.5 kHz,4.5kHz以上,通带衰减Rp=0.5dB,阻带衰减As=10dB。
4)带阻:阻带2kHz~4 kHz,通带0~1.5 kHz,4.5kHz以上,通带衰减Rp=0.5dB,阻带衰减As=10dB。(Using MATLAB to implement the design of IIR filters: impulse invariant and bilinear transformation)
