| 1. | Also , cathode bias circuits ( with bypass capacitors ) are not very successful , since for dc bias purposes , the cathode resistor presents a high dc resistance equivalent at the anode , and the quiescent point is not very stable 而且,阴极偏压电路(带旁路电容)也很难成功,因为直流偏压的原因,阴极电阻在屏级上表现出很高的等效直流电阻,这样静态工作点很难得以稳定。 |
