摘要
讨论了测试信号预处理消除趋势项的两种方法——平均斜率法和最小二乘法,使用美国NI公司虚拟仪器开发环境——LabVIEW对算法进行了仿真,并对这两种方法进行了比较。
This paper discusses on two methods of eliminating the tendency item in the signal pre-processing, the mean slope method and the least square method, and simulates the algorithms by using the virtual instruments developing environment, LabVIEW, of American NI Company, and makes comparison of these two methods.
