电视OTL场扫描输出电路

The OTL Vert Scannimg Output Circuit of Television

简述了ＯＴＬ场扫描输出电路的工作原理，分析了各阶段电流、电压波形形成的过程及特点。在此基础上讨论了该电路的各元器件变质变化对电视机工作的影响。

In this paper, the working tenet of OTL vert scanning output circuit is presented, the proabases and charateristics tating the shape of the currents and voltages of all phases of the circuit are analysed. And based on this, the effects to television work are disscussed, when a certain element or device of the circuit has ben worally degenerate or one's parameters have changed.
