摘要
同步脉冲是控制录音机播放的解说词和图板显示同步的关键。本文主要介绍了声光显示图板控制电路的工作原理和电路结构，着重描述了同步脉冲在录音磁带上的录制与取出电路，文中给出的电路及电路中各元器件的型号和参数，都是作者所设计的声光显示图板控制电路中已应用的，应用效果良好。
Synchronizing impulse is the key to synchronize sound playing with light displaying of graph plate.This paper discribes the principle and the structure of the control curcuits of the graph plate,focuses attention on the recording and restoring curcuits of synchronizing impluses from or to cassatte tape.The parameters of every components of the curcuite are being used in the control curcuits of the graph plate,which were designed by the authors of the paper.The applying result is very good.
