摘要

本文的目的是介绍沃尔什-阿达玛变换在猪子宫收缩活动的肌电信号分析中的应用。傅里叶谱分析在生物医学领域有着广泛的应用。然而，对于二进制时间序列，基于峰值为±1的方波或矩形波的Walsh-Hadamard变换更为准确。优势归一化序列可以作为描述生物医学信号的参数，具有重要的诊断意义。

Walsh-Hadamard spectral analysis of signals representing bioelectrical activity of the reproductive tract in pigs

The aim of this paper is to present the use of the Walsh-Hadamard transform in the analysis of electromygraphic signals representing the uterine contractile activity in pigs. The Fourier spectral analysis is widely used in many biomedical applications. However, for binary time series the Walsh-Hadamard transform based on square or rectangular waves with peaks of ±1 is more accurate. Dominant normalized sequency can serve as a parameter describing the biomedical signal, which may have diagnostic importance.
