AMPLIFYING AND ALLOTTING SYSTEM FOR USE IN WIRE BROADCASTING

摘要

The invention first relates to a choke coil for transmitting cable broadcast distribution amplification device in particular, only the voltage on the voltage and the broadcast signal from the source is transmitted through the side of the track, and then amplification of the distribution device and; Separating the broadcast signal from the broadcast signal from the voltage and are transmitted through the source signal line and the branch; The first diplexer, which by mutually separating the video signal data and the low frequency signals of high frequency in the broadcast signal; Which amplifies the image and the data signal at a constant level and the first and second amplifiers; The second diplexer, which by mutually separating the video signal data and the low frequency signals of high frequency in the broadcast signal transmitted from the subscriber; To remove the various noise signals included in the broadcast signal to be input and passes only the pure broadcast signal and the low-cut filter; The low-cut filter the transmitted matcher Greater broadcast signal distributor for distributing the broadcast signal over a number of taps to each other and the antenna impedance matching for the subscriber's TV set through the; A second choke coil for taking out only the voltage on the voltage and the broadcast signal from the source is transmitted through the track; AC voltage a to the rectifier at a constant DC voltage that can be configured as a switched mode power supply provided in each part to prevent the variation of the degradation of the service, the signal level in advance, as well as reduce the labor and installation costs associated with the installation of the amplifier and, to preclude the use of a pair cable will allow you to significantly reduce installation costs and labor costs.
