3-1试述行扫描电路与场扫描电路有什么相同点与不同点?答:行扫描电路与场扫描电路都是产生锯齿波电流,分别送入行、场偏转线圈使电子束不断的进行扫描,这是两者的相同处.但两个电路的工作状态有较大差别,场扫描电路中,在场振荡器后的场推动级与场输出级是放大器,与音频放大器类似,所以它可以采用OTL输出功率放大器和扼流圈耦合的输出放大器,晶
3-1 test line scanning circuit and field scanning circuit what are the same and different? A: The line scanning circuit and the field scanning circuit are generated sawtooth wave current, respectively, into the line, the field deflection coil so that the electron beam continues Scan, which is the same place between the two.But the working state of the two circuits are quite different, field scanning circuit, after the field oscillator field drive stage and field output stage is an amplifier, similar to an audio amplifier, so it can Using OTL output power amplifier and choke coupled output amplifier, crystal
