摘要

本文将仪器的细节放在一边，以揭示测量所解决问题的本质。它的标题是基于1894年埃尔顿教授和他的学生海克拉夫特的一篇论文的标题。他们描述了一种新的和简化的测量方法，以改善他们的基础主题的教学，这就是本文的目标。在这里描述的工作中，测量值被认为是一个表示交流信号的方程，而测量值的声明值是方程参数的估计值。结果表明，通过曲线拟合可以得到交流信号的参数。我们可以从噪声在测量中的作用和测量结果的意义中得到教训。

Students' simple method for determining the parameters of an AC signal

The paper sets aside details of instrumentality to reveal the nature of the problem addressed by measurement. Its title is based on the title of a 1894 paper by Prof. W.E. Ayrton and his student H.C. Haycraft. They described a new and simplified method of measurement to improve the teaching of their underlying topic, and that is the goal of this paper. In the work described here, the measurand is taken to be an equation representing an alternating signal, and the declared values of the measurement are estimates of the parameters of the equation. It is shown that the parameters of the ac signal can be found by curve-fitting. Lessons can be drawn about the role of noise in measurement and about the very meaning of the result.
