METHOD FOR MEASUREMENT OF TWO VOLTAGE RATIO Russian patent published in 1994 - IPC

FIELD: electric measurement technology. SUBSTANCE: method consists in that formed from levels of high input, first reference and low input voltages are first, second and third respectively, linearly decreasing auxiliary voltages with steepness proportional to high input, reference and low input voltages, respectively. Sought ratio of low input voltage-to-high input voltage is determined by measurement results of second auxiliary voltage and the moment of equality of first auxiliary voltage and low input voltage, and sought ratio of high input voltage-to-low input voltage is determined by the result of measurement of first auxiliary voltage at the moment of equality of third auxiliary voltage and second reference voltage. EFFECT: higher efficiency. 2 dwg
