  • Double duty capacitor circuit and method
    Patent number: 5528682
    Abstract: A method and circuit in which two filters connected to different inputs that do not operate at the same time share a common capacitor to thereby reduce the number of capacitors needed for the circuit. A filter that is connected to an input that is not operating may be selectively disabled by connecting a resistor form the disabled filter and the common capacitor to ground when the other input is being operated. The method and circuit find application in a telephone system in which a filter connected to a subscriber line interface circuit (SLIC) and a filter connected to a telephone system circuit that does not operate at the same time as the SLIC share a common capacitor.
