摘要
为了准确地测量记录各种被测信号 ,应当正确地选用振子的固有频率和阻尼 ,适当地选取被测信号的大小 ,保持信号源内阻Ri 与振子的内阻rg 相匹配 ,同时要正确地调整光点位置 。
In order to accurately measure and record vavious kinds of signals which need to be measured, we need to correctly select the nature frequency and damping of os cillators, properly select the magnitude of the signals, keep the internal resis tance R i of the measured singnal source match with the r g of the osc illator, and also properly adjust the position of the light dots, so that the ar c errors are reduced.
