物理实验中示波器法测量RLC串联电路相频特性的实验要[1],形象直观;但要从荧光屏上测出距离换算成相位,读数不准又费时,而且被测的两条图线是通过重复交替扫描所得,并不能保持它们原来的相位关系.随着新技术的引进,我们将微机应用于此实验,取得了较好的效果. 一、实验装置与测?
Physical experiment oscilloscope method to measure the RLC series circuit phase frequency characteristics of the experiment to [1], the image is intuitive; but to measure the distance from the screen converted to the phase, the reading is not allowed and time-consuming, and the measured two lines through Repeatedly scanning the results obtained, and can not maintain their original phase relationship.With the introduction of new technology, we will use the computer in this experiment, and achieved good results. First, the experimental device and measurement?
