Usually it can be adjusted to sync location by the circuit . When the error is 180 ° it may lead to false sync .

通常 系统能调整到 协调位置，而当误差角为180°时，会出现假同步。

On the property of the TV horizon scan sync circuit

电视机行 同步 电路 的 电路属性

The sync control circuit is one of keys to influence stability of trigger system of SCR are welding .

同步控制 电路是影响晶闸管整流弧焊机输出稳定性的一个关键。

Accepted picture output two streams from one of which the composite sync outputs needed by chip for video characters overlapping is separated in the video sync separator . The other is input of the video amplifying circuit to drive the signal .

接收到的图像信号分两路，一路进入 同步 信号分离器，分离出字符叠加芯片所需的复合同步信号，另一路进入视频放大 电路，对信号进行驱动。

Having analysed and contrasted the AFC circuit and the APC circuit and then having tested and verified it through experiments the writer advance a new viewpoint : the TV horizon scan sync circuit should belong to APC circuit but not as usual AFC circuit .

作者通过对AFC电路和APC电路的分析和对比，并且通过实验加以验证，提出一个新的看法，认为电视机行 同步 电路，应属于APC电路，而不是通常所说的AFC电路。
