Abstract

PURPOSE:To make it possible to manufacture a circuit of simple constitution cheaply, by using only one differential amplifier. CONSTITUTION:Only one differential amplifier A3 is used. Once only one couple of scanner switches 7a and 7b are selected and turned ON, circuit B is connected to amplifier A3 to constitute the complete differentialamlifier circuit, so that the removing of in-phase noises and insulation will be performed. For the purpose of the improvement of in-phase component removing characteristics of the differential amplifier, respective resistances are set under the condition of (resistance value of input resistance 2)>(resistance value of protective resistance 3a)>=(esistance value of in- phase voltage balance reistance 3b).
