Abstract

PURPOSE:To equalize a relatively-large amplitude deviation regardless of the fractional band width by a simply-constituted circuit by varying frequency characteristics to signal amplitude. CONSTITUTION:In the amplitude equalizer which has signal input terminal 10 and signal output terminal 11 and certain characteristics of signal amplitude to a frequency, branch or synthesizer circuit with the 3rd terminal 16 is connected between input terminal 1 and output terminal 11. Further, the circuit composed of delay circuit 13, phase shifter 14 and variable impedance circuit 15 is connected to the 3rd terminal 16 of circuit 12 to transmit waves reflected by variable impedance circuit 15 of this circuit to output terminal 11. Then, the impedance of variable impedance circuit 15 and the delay amount of delay circuit 12 are varied to vary characteristics of signal amplitude to a frequency, thereby making it possible to equalize a large amplitude deviation regardless of the fractional band width.
