Abstract

PURPOSE:To reduce the effect of the voltage fluctuationby offsetting the output of the 1st balanced amplifier circuit and then supplying it to the 2nd balanced amplifier circuit, and thus to ensure the adjustment of the offset voltage to the input signals of a wise band. CONSTITUTION:The input signals applied to input terminal 1 and 2 are amplified at 1st balanced amplifier circuit 6 and then receive the gain adjustment at gain control circuit 10 to be amplified again at 2nd balanced amplifier circuit 9. Then the adjustment is given to the offset voltage by variable resistance element 5 and via the output voltage of circuit 6.
