IIR
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。

HDB3decoding
数字基带信号的传输是数字通信系统的重要组成部分。在数字通信中,有些场合可不经过载波调制和解调过程,而对基带信号进行直接传输。HDB3码的作用是对数字基带信号进行编码,便于在接收端对定时分量的提取。(Digital baseband signal transmission is an important part of digital communication system. In digital communication, some occasions without carrier modulation and demodulation process, and to direct transmission baseband signal. HDB3 code is used to encode digital baseband signal, facilitate at the receiving end of timing component extraction.
