In a cathode-biased amplifier, the bias voltage is developed across a cathode resistor that is bypassed with a big electrolytic capacitor. 在阴极偏置放大器,偏置电压是发达国家之间的阴极电阻是绕过一个大电解电容器。
The presence of a cathode bias resistor and bypass capacitor is not an indication of class A operation. 在场的情况下阴极偏置电阻和旁路电容不能说明A类作业。
