Abstract
Description
The frequency responses of a single-phase powerline channel with interconnections are derived. Different
loading at different branches is considered. The results indicate that there are significant attenuations and
distortions as the number of branches are increased. Broadband signal with pulse width smaller than the
channel delay spread causes a series of pulses at the receiver. The small impedances at the terminations cause
severe distortions. As the number of interconnections at the same point increases the signal from the source to
that point increases in negative sides, which has implications to electromagnetic interference.
