Abstract

A regenerator for providing detection, remodulation, and retransmission of a digital data signal propagated in the differential mode over a pair of bundle conductors of a power line. The electric power signal, propagated in the common mode over the same bundle conductors, is conducted through the regenerator and provides a power supply voltage for the regenerator electronics. A series of electrical traps prevent the electric power signal from being conducted into that portion of the regenerator utilized for processing of the data signal. The regenerator also includes bypass switches for by-passing the regenerator electronics when a power supply voltage sufficient to operate the electronics is unavailable.
