ABSTRACT:
The invention is comprised of two inductors wound in series but in opposite directions around a ferrite core, a resistor being connected in parallel with one inductor, and a wire being looped through a ferrite bead and being wound around the other inductor. The invention allows a 60 Hz power signal to pass without excessively interfering with radio frequency signals in excess of 900 MHz and preferably on the order of 1 GHz. The invention is particularly useful in cable television systems, where a power signal and an RF signal are sinultaneously transmitted.
