Abstract

PURPOSE:To make constitution simple and make it possible to perform operation of high accuracy by performing direct operation with input voltages in an analog operator utilizing composite photocouplers and an inversion amplifier. CONSTITUTION:The output voltage E0 obtainable from between the output terminals (h) and (i) of an inversion amplifier when an input voltage EiA is applied to the input terminals (a), (b) of an amplifier A1, an input voltage EiB to the input terminals (a'), (b') of an amplifier A2 and an input voltage EiC to the input terminals (f), (g) of the inversion amplifier, respectively, assumes the result that the product of the input voltages EiC and EiB is divided by the input voltage EiA. Hence, the direct operation is performed by the input voltages and since the effect of temperatures is compensated, the operation of high accuracy is performed.
