This is the first of a series of four tutorial papers on biomedical signal processing. It provides an introduction to terminology and basic ideas for testing for randomness and trend, and for the determination of basic signal properties in the time domain, given the uncertainties associated with the estimation process. Techniques outlined in the paper are: the coherent average, cross-correlation and covariance, autocorrelation and phase-shift averaging.
这是关于生物医学信号处理的四篇系列教程论文中的第一篇。它介绍了一些术语以及用于测试随机性和趋势、在存在与估计过程相关的不确定性的情况下确定时域中基本信号特性的基本概念。本文概述的技术有：相干平均、互相关与协方差、自相关以及相移平均。
