Abstract

PURPOSE:To secure a quick and accurate grasping of the equalization distribution for the repeating transmission line by detecting the difference through the power difference detector between the monitor oscillator output and the repeater transmission output and modulating the monitor oscillator by the output signal to transmit the output together with the transmission signal output.
