ABSTRACT:
A capacitor coupled circuit includes a power supply switch for switching power supply on; a coupling capacitor provided in a signal line; and a control circuit arranged to cause the capacitor to be charged or to be discharged in a short period of time according to the operation of the power supply switch. The arrangement enables the capacitor coupled circuit to obtain a stabilized constant output voltage in a short period of time after the power supply is switched on.
