Abstract
A wireless transmitter includes a first filtering unit coupled to a first cable for outputting a first DC source transmitted on the first cable, a first power converting unit for converting the first DC source into a second DC source, a second filtering unit for eliminating noise in the second DC source, a first DC blocking unit for blocking the second DC source and outputting a second frequency modulation (FM) signal, an amplifier for amplifying the second FM signal to generate a first FM signal, and a second DC blocking unit coupled to the amplifier and the first cable, for outputting the first FM signal to the first cable, such that the first FM signal is transmitted to the air through the first cable as a transmitting antenna.
