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: 用双线性变换法设计IIR数字滤波器
（1）用双线性变换法设计一个巴特沃斯低通IIR 数字滤波器。设计指标参数为：在通
带内频率低于0.2π 时，最大衰减小于1dB；在阻带内[0.3π ,π ] 频率区间上，最小衰减大于15dB。
（2）以0.02π 为采样间隔，打印出数字滤波器在频率区间[0,π / 2] 上的幅频响应特性
曲线。
（3）用所设计的滤波器对实际心电图信号采样序列（在本实验后面给出）进行仿真滤
波处理，并分别打印出滤波前后的心电图信号波形图，观察总结滤波作用与效果。
