Abstract

A termination circuit for N power distribution lines has resistances rjj connected between points Pj on N-l of the lines and between the points Pj and a ground, which is connected to the remaining one of the lines. The termination circuit as defined above can include isolation capacitors in the lines for isolating power signals distributed on the lines from a communication signal having a high frequency relative to a frequency of the power signals.
