| 摘 要： | 针对传统过零频率检测方法对信号噪声与干扰抑制能力不强的特点,以及数字检测系统中存在最小相位分辨率等问题,提出一种基于一元线性回归理论的数字正弦信号频率测量算法.算法基于数理统计原理,数据分析不在乎信号过零点的准确位置以及单点信号值的准确程度,而是对信号零点附近的多点数据进行数值统计,因此对外界信号噪声及于扰有很强的抑制...

| Abstract: | In order to improve the signal noise and interference suppression capability for the traditional method of zero-crossing frequency measurement,and to solve the minimum phase resolution problem of digital measurement system,this paper presents a linear regression theory based frequency measurement algorithm for digital sinusoidal signal.The algorithm is based on principles of mathematical statistics,and the data analysis does not care about the exact location of zero-crossing signal and the accuracy of the s... |
