d AC two paths shown in Figure 1-14. The DC path to provide a DC bias circuit of the circuit from the power transistor, the transistor is in an enlarged state or the off state, it is mainly determined by the bias. This circuit also provides energy for the transistor circuit. AC AC signal path is functioning circuit, a capacitor AC signal can be regarded as a short circuit, the internal resistance of the power supply also depends on the AC signal is short-circuited.
