DEVICE FOR EXTRACTING SQUARE ROOT FROM SUM OF SQUARES OF TWO QUANTITIES Russian patent published in 1995 - IPC

FIELD: measurement technology to function as position transducer. SUBSTANCE: device implements relationship , where K1= U_max/U_min, and factor K_o(i) twice changes its value in response to changes in K1. Device has two modulo separation units, dividing unit, comparison unit, controlled voltage divider, two reference-voltage source, and adder. EFFECT: improved measurement accuracy at output signals changing within wide dynamic range, reduced measurement error not to exceed 0.37 2 dwg
