ABSTRACT:
A self-balancing telephone-type hybrid having two sets of conjugate ports, wherein conjugacy is maintained between receiving and transmitting ports despite wide variations in impedance conditions at the line and/or balance ports. Included are means of differentiating between bridge unbalance due to impedance unbalance and that due to a signal being injected into the line port.
