摘要
本文经理论分析得到了一种采样频率与信号频率的简单关系,按着这种关系选择采样频率就容易消除初相位的影向。还给出一种由数据平方和求信号幅值的方法。
A simple relationship between sampling frequency and signals frequency has been given in this paper through theoretically analysing. It can eliminate the affection of first phase easily by this relationship to choose the sampling frequency. A method has been given to get signals range from the square sum of data.
