基于RC 惯性环节自动控制的线性 电子锯齿波产生器 高萍，刘国贤，侯健生 （华北电力大学电气与电子工程学院，北京，102206） Linear Electronic Sawtooth Wave Generator Based on the RC Inertia Tache of Auto-control GAO Ping ，LIU Guoxian ，HOU Jiansheng (North China Electric Power University,Beijing 102206 ) Abstract :Sine wave 、rectangle wave 、triangle wave and 光屏上不失真地观察到被测信号波形，要求在水平 sawtooth wave are all the basal testing signals in common use. 偏转板加上随时间作线性变化的电压—— 锯齿波 And in some apparatuses such as the oscillograph and the 电压，使电子束沿水平方向匀速有哪些信誉好的足球投注网站荧光屏。而电 television, to make electrons move in the specific rule in order 视机中显像管荧光屏上的光点，是靠磁场变化进行 to show the image with fluorescence screen, a sawtooth wave 偏转的，所以需要要用锯齿波电流来控制。但目前 generator is always used as the time base circuit. But its easy 好多锯齿波产生器普遍很容易产生诸如元件损环 for the general sawtooth wave generator to come forth such 等小问题。但就是这些小问题却经常会影响锯齿波 faults as the element with something wrong, and then it may 的正常产生，会使锯齿波波形发生各种意外的突 influence the creation of the normal sawtooth wave. Therefore, 变。针对此，笔者就自己的认识和研究，在对其分 the writer devise a set of generator including the generating、the 析的基础上自行设计出一套集产生、振荡、加工、 shaking and the linear amending on the basis of theoretic 线形校正于一体的电子锯齿波产生器，同时给出了 analysis ,with great concentration researching. At the same 产生器的检修方法。 time a way of examination and repair is given. And graphic 1. 典型的锯齿波产生器 illumination is also presented especially. It has been proved 典型的锯齿波产生器的结构方框图如图 1 所 that the set has received preferable effect. 示： Key word: sawtooth wave; generate ; shake; emend. 摘要：锯齿波和正弦波、矩形波、三角波是常用的基本测试 锯齿波振荡 锯齿波加工 上线形校正 信号。而在如示波器、电视机等仪器中，为了使电子按照一 定规律运动，以利用荧光屏显示图像，常用到锯齿波产生器
