摘要

现代数字存储示波器提供了一个直观观察几乎任何形式的研究信号的机会。与计算机接口的能力使您可以实现更大,几乎无限范围的信号处理和分析任务。本文以几种灯具和照明装置为例,对其光通量脉动系数进行了测量。测量结果表明,信号可能会有很大的噪声。解决方法是对信号进行后处理,逐步去除噪声,并计算必要的特征。Mathcad被选为数学处理器。根据得到的纹波函数的最佳质量,对处理方法进行了实验选择。所采用的方法表明,即使在所研究的信号有明显噪声的情况下,它们也是有效的。

The Use of a Digital Oscilloscope and Mathcad to Determine of the Pulsation Coefficient of Various Lighting Device
Modern digital storage oscilloscopes provide an opportunity to visually observe the studied signal of almost any form. The ability to interfacing with a computer allows you to implement an even larger, almost unlimited range of tasks for signal processing and analysis. As an example in this paper was carried out by measurement of the pulsation coefficient of the light flux for several variants of lamps and lighting fixtures. As the results of measurements showed, the signal can be very noisy. The solution is to post-process the signal with the gradual removal of noise and calculate the necessary characteristics. Mathcad was chosen as the mathematical processor. The choice of processing methods was carried out experimentally, based on the best quality of the obtained ripple function. The methods used have shown their effectiveness even in the case of significant noise of the studied signal.
