BRIDGE METER OF PARAMETERS OF MULTIELEMENT PASSIVE TWO- TERMINAL DEVICES Russian patent published in 2000 - IPC

FIELD: measurement technology, measurement of parameters of passive two-terminal devices having multielement equivalent circuit. SUBSTANCE: generator of sequences of voltage pulses supplying four-arm electric bridge has one former of voltage pulses of cubic form. For stage balancing of electric bridge output of differential amplifier connected with its inputs to measurement diagonal of bridge and outputs of three differentiators connected in series are linked to inputs of null-indicator. Input of one differentiator is tied up together with output of differential amplifier. Voltages across outputs of third, second and first differentiators and differential amplifier are sequentially brought to zero value in process of balancing of bridge. EFFECT: simplified design of bridge meter. 1 dwg
