PURPOSE:To simplify the constitution and to increase the accuracy, by performing the processing of multiplication effectively, through the supply of the input signal and the reference signal to a plurality of integrators for a given time. CONSTITUTION:The sum signal of the input signals x and y is integrated for a given time with the integrator 3, the integrated value output is held 5, the integrated value is inversely integrated by given the reference signal E1 to the integrator 3, and the holding value of the circuit 5 is integrated 8 by the inverse integration time. Further, after the operation of the integration and inverse integration of the integrator 3, the defference signal between the signals S and Y is integrated 3 for a given time, and after holding 5 the integration value, inverse integration is made with the signal E1, the integration value of the difference signal of the circuit 5 is inputted to the integrator 8 by the period of the inverse integration, the integration value of the sum signal is inversely integrated, and after the input of the reference signal E2 to the integrator 8 is made and inverse integration is made, and the multiplication value of the signals X and Y can be obtained from the inverse integration time. Each operation timing in this case can be obtained from control circuit 11. |
