DEVICE FOR CALCULATION OF SQUARE ROOT OF SUM OF SQUARES OF THREE VALUES

摘要

FIELD: computer engineering. SUBSTANCE: device has three units for calculation of absolute values, which inputs serve as inputs of device, amplitude selector, dividing unit, two controlled voltage scaling units, comparison unit, two reference voltage power supply units, adder with controlled gain. Output of adder serves as device output. Device may be used as function generator for calculation of vector absolute value. It measures ratio of absolute values of input signals and changes gain of adder depending on value of K₁. Method error and instrumental error in wide dynamic range of input signals is about 1%. EFFECT: increased precision of calculation of vector absolute value. 2 cl, 3 dwg
