ABSTRACT:
This disclosure depicts a build out capacitor for use with a voice frequency loaded pair having tip and ring terminals. The circuit comprises means for providing a virtual impedance between the tip terminal and ground and between the ring terminal and ground. The means has a first input connected to the tip terminal and a second input connected to the ring terminal. The means for providing also has first and second outputs. A first fixed capacitor is connected between the first output and the tip terminal and a second fixed capacitor connected between the second output and the ring terminal. The first capacitor is equal in value to the second capacitor.
