Abstract
PURPOSE:To constitute a non-linear arithmetic circuit which is easily adjusted and provides linearization with high approximation. CONSTITUTION:Circuits 2 and 3 outputs k1Ei and + or -k2Ei by receiving input signal Ei and curcuit 4 receives output Ef of multiplier 1 and outputs + or -k3Ef; and Em= + or -k2Ei+ or -k3Ei is obtained by adding 5 and multiplication of Ef=EiEm is performed. With (k3) less than one, addition 6 to k1Ei is done to obtain non-linear arithmetic output EO=k1Ei+ or -k2Ei<2>+ or -k2(+ or -k3)Ei<2> at terminal 8. Therefore, values of coefficients (k1)-(k3) are set adequately and signal Ei equivalent to electromotive force of a thermocouple is inputted so as to lonearize a non-linear error with a high approximation degree by an equation of the 3rd degree. In case of a platinum resistance thermometer bulb, coefficient (k2) is set positive and (k3) is to zero, so that linearization can be attained by an equation of the 2nd degree.
