PURPOSE:To manufacture the titled mixer without taking cis-matching into consideration and to completely eliminate multiple ghosts, by giving a directional property to video signal strips by inserting an amplifier and by absorbing reflected waves from a branched wave mixer of the later stage. CONSTITUTION:A video signal from a center is inputted into the terminal 21 of a two-way branched wave mixer and outputted to a terminal 28 after passing through an LPF 27. An output video signal from a terminal TV set is inputted into an input terminal 29 and then outputted from an output terminal 23 to the next two-way branched wave mixer of the next stage through an amplifier 30 and an LPF 31. On the other hand, an income or control signal carrier is inputted from a terminal 22 and mixed with that of the main line series by a mixer 25. The mixed product is sent to the center from the input terminal 21 through an HPF 24. |
