6, decoupling capacitor (decoupling Capacitor) : is a circuit mounted capacitor power end element, this capacitor can provide a more stable power supply, while the element is coupled to the power supply terminal can also reduce noise , it can indirectly reduce other element by this element the effect of noise, the main function is to provide a more stable power supply. Also referred to as decoupling capacitors decoupling capacitor is to filter out the interference signal as the output target ,, where ships do not need to communicate on, to eliminate the self-oscillation, in a steady-state operation of the amplifier. Decoupling capacitor is to function as a battery, to meet the driver circuit changes in current, to avoid mutual interference coupling.
Bypass capacitor (Bypass Capacitor) : is the high frequency noise in the input signal as the filtered target, the front-stage carrying a high frequency noise filtered
