Abstract
An adjustable balancing circuit (,) for an adaptive hybrid is suitable for use with a two-conductor transmission line in full duplex communications. In a preferred example, the adjustable balancing circuit (,) includes a first impedance structure (,), a second impedance structure (,), a plurality of N resistor-inductor-capacitor (RLC) networks (,), a first plurality of N switch circuits (,), and a second plurality of N switch circuits (,). The first plurality of N switch circuits (,) switchably cascadingly couples the first plurality of N RLC networks (,) to a first end of the first impedance structure (,). The second plurality of N switch circuits (,) switchably couples a first end of the second impedance structure (,) to a first end of each RLC network. When properly configured, the adjustable balancing circuit (,) cancels reflected transmit signals caused by the presence of short bridged taps on the two-conductor transmission line.
