Abstract
PURPOSE:To always realize the best transmitting characteristics, by inputting a part of the output signal of an amplitude equalizer, and controlling the equalized quantity of the amplitude equalizer so that the peak values of the two types of the frequency elements of a multi-burst signal in a TV signal may be the identical. CONSTITUTION:The TV signal inputted to a signal input terminal 1 is transmitted through a coaxial cable 2, a frequency equalizer 3 and a signal output terminal 4 to the TV receiver set in a separate place or to a transmitting device on a receiving side. A part of the output signal of the frequency equalizer 3 is removed by a signal branching device 5, and supplied to a controller 6. The controller 6 respectively detects two types of the peak values of the multi- burst signal in the TV signal, for example the peak value of a minimum frequency element and a maximum frequency element, and controls the amplitude equalizer 3 so that both the peak values may be the identical. Thus, the amplitude equalizing adjustment is easily attained.
