Abstract
A cable television apparatus is applied to an input coaxial cable and an output coaxial cable to transmit a cable television signal and an alternating current power. The cable television apparatus includes a high saturation current transformer, an input terminal, an output terminal and a coupling side. The high saturation current transformer includes a ferrite core, a primary side circuit and a secondary side coil. The ferrite core is a high saturation current ferrite core, so that the primary side circuit transmits the cable television signal and the alternating current power, and couples the cable television signal to the secondary side coil.
