ABSTRACT:
The hybrid includes a control circuit which automatically matches the impedance of the balancing network to the input impedance of the two-wire line connected to the hybrid. For control, rectified voltages present on the two-wire side and across the balancing network are averaged over time and the mean time values are compared.
