Abstract
PURPOSE:To give bidirectivity only to the signal in specific frequency and to give unidirectivity to television signal, by connecting the bidirectional generating element of specific frequency to the secondary winding of a transformer constituting the branch element. CONSTITUTION:The (c) side of the secondary winding L2 of a brancher is connected to the branch terminal 10, and the (d) side is connected to the (h) side of the specific frequency bidirectional generating element 16. Thus, in the signal of television broadcast, unidirectivity is given and bidirectivity is given to the signal in the frequency band selected, then spurious radiation leaked from the local oscillator of a television receiver can be prevented from being flowed to the post stage of the receiver through back flow from the branch terminals, and further, the adverse effect to the video quality of the television receiver connected to the branch terminal of the prestage branch device can be avoided, and the loss of communication line between them can remarkably be reduced, allowing the communication with high articulation.
