| 摘 要： | 详细介绍了一种以DSP为核心的心电监护仪的简单整系数数字滤波算法。首先根据干扰的不同,使用MATLAB软件设计各种数字滤波器,并进行仿真后得到各种滤波器系数,最后就如何在DSP的开发软件CCS上实现做了详细分析和仿真。结果显示,该方法在不减弱原始心电信号的基础上能够有效地滤除心电信号中的杂波。

| Abstract: | A sample integer coefficient digital filter method which uses the DSP as the core is introduced in detail in this paper. Firstly, kinds of digital filters are designed by the soft MATLAB according to sources of noises and gains kinds of coefficient. Lastly it introduces how to achieve by DSP. The results indicate this method can filter the noise without weaken the originality heart signal. |
