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。

IEC60601-1-8音频报警标准提供了富有和声的音调,以便使它们容易定位、并能防止屏蔽的干扰。范畴与对应旋律的数量都有限,从而能获得容易掌握的不同报警顺序。另外,报警的优先权决定了报警中音符的数量,以及音符顺序的动态特征。这使得人们容易确定报警的紧急程度。这样,IEC60601-1-8标准解决了许多以前报警的限制因素,而且将有助于改善患者的安全性。(IEC60601-1-8 standard audio alarm provides a rich harmonic tone in order to make them easier to locate and prevent interference shielding. Areas and have limited the number corresponding to the melody, so that it can be easy to grasp the order of the different alarm. In addition, the alarm priority determines the number of alarm in the note, and note the order of the dynamic features. This makes it easy to determine the urgency of the alarm. This, IEC60601-1-8 standard solution before the alarm of many constraints, but will also help improve patient safety.)
