METHOD FOR MEASURING AVERAGE VALUE OF VOLTAGE OF ARBITRARY SHAPE AND DEVICE FOR IMPLEMENTATION OF SAID METHOD Russian patent published in 1995 - IPC

FIELD: instruments. SUBSTANCE: method involves detecting sum and difference of reference voltage from source 3 and voltage that is proportional to measured level. Scaling coefficient a and b are determined by scaling units 13 and 14. Said sum and difference are integrated by integrators 1 and 2 correspondingly. If one value is greater than another, the former is changed to latter as exponential function by closing switches 9 or 10. During interval while value changes, functional value is generated following pre-given function F(t). Value of this function at the moment when initial values are equal determines average value of measured voltage. EFFECT: increased functional capabilities. 6 cl, 6 dwg, 2 tbl
