| Abstract: | 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. |

| Keywords: | Nature frequency Damping Impedance matching Position of light dots |
