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.
