Abstract
FIELD: instrumentation, measurement of parameters of multielement two-terminal networks. SUBSTANCE: method is based on integration of voltage across output of two-terminal network with reference element Ro, by operational amplifier. Exponential action is fed to input of two-terminal network and first value of specified voltage integral H2 is measured at time moment tp and second value of specified voltage integral H3 is measured at time moment 2tp in process of integration of output voltage. Known exponential caused by input action is filtered from obtained values of integrals, comparison operation is executed, value of index p2 and value A of amplitude of transient process across output of two-terminal network are computed. Thereupon parameters of two-terminal network for series RC circuit are computed. EFFECT: increased accuracy in determination of parameters of multielement two-terminal networks based on use of exponential action with the aid of integration operation only. 10 dwg
