Circuit for broadband video transmission over unshielded twisted wire pairs |
摘要 |
Disclosed is a circuit which permits transmission of broadband analog CATV video signals on unshielded twisted wire pairs. The circuit includes an autotransformer with a ground connection coupled to the node between two secondary windings. The two opposite ends of the secondary windings are coupled to a choke, which, in turn, is coupled to an isolation transformer with a center-tapped primary and secondary winding for shunting any remaining common-mode currents.
