DEVICE FOR SIGNALS ANALYSIS IN REAL TIME Russian patent published in 2015 - IPC G01R23/16 

FIELD: instrumentation.

SUBSTANCE: device additionally contains 2 additional assembly groups, each of them contains connected in series ROM unit, analogue-digital multiplier, analogue integrator with reset, and block of absolute signal value determination, where k is total number of scanning sine signals during spectrum analysis, and including of the additional analogue summation unit and output analogue summation unit, where inputs of the included ROM units are connected with outputs of the address generating counter, analogue inputs of the analogue-digital multipliers are connected to the input busbar, outputs of units of signal absolute value determination are connected to inputs of additional analogue summation unit.

EFFECT: increased accuracy of measurements of harmonic component amplitudes.
