叙述了一种电测的系统方法,可以帮助理解多种测量方法。该方法的实质是将各种测量问题或者测量装置统一视为一个系统的特例,而该系统的功能则是由信号处理来完成的。以此方法,测量理论与给定测量问题的实现之间的对应关系,以及各种测量之间的相似点与不同点将变得一清二楚。文中对若干例子进行了讨论。 Describes a system of electrical measurement methods that can help understand a variety of measurement methods. The essence of this method is to treat all kinds of measurement problems or measuring devices as a special case of a system whose function is performed by signal processing. In this way, the correspondence between the measurement theory and the realization of a given measurement problem, as well as the similarities and differences between the various measurements, becomes clear. Several examples are discussed in this article.
