专利的详细说明:本专利是有关将来白天线的超高频、甚高频信号通过一根电缆接到电视输入端的电视显像方式,目的在于不使用分配器即可收到的超高频、甚高频信号分别输入到超高频、甚高频调谐器里。以前,甚高频及超高频信号借助于一根同轴电缆输入到电视机调谐器里时,进入到混频器10里的超高频及甚高频信号如图1所示,通过分频器11分离后,进入到甚高频调谐器1及超高频调谐器5里。可是,这种方式,不仅需要有分频器,而且还需要分别由分频器向甚高频调谐器及超高频调谐器进行布线,并且,还十分复杂。
Patent Details: This patent is about the future of white antenna UHF, VHF signal through a cable connected to the TV input of television imaging, the purpose is not to use the distributor to receive ultra-high frequency, Vhf signals were input to UHF, VHF tuner. In the past, when VHF and UHF signals were input into the TV tuner by means of a coaxial cable, the UHF and VHF signals entering the mixer 10 are shown in FIG. 1, After the frequency converter 11 is separated, it enters the VHF tuner 1 and the UHF tuner 5. However, this method not only requires a frequency divider, but also needs to be routed from a frequency divider to a VHF tuner and a UHF tuner, respectively, and is still quite complicated.
