FIELD: instruments. SUBSTANCE: device, which is function generator which outputs signal proportional to 
, uses negative feedback when system tries to keep level of mismatch signal at output of comparison unit. Signal to be compared 
and signal 
are kept equal. When they are equal, device outputs signal which is proportional to 
. Compared signals are kept high even if signal X lowers its level. Device has unit for calculation of square root from sum of constant and variable values, which input serves as input of device, comparison unit, amplifier, integrator, adder and unit for calculation of square root from sum of constant and square of variable. EFFECT: precision of calculation is at least doubled when input signal is low. 1 dwg
