DEVICE FOR MEASURING AMPLITUDE AND PHASE CHARACTERISTICS OF HARMONIC SIGNALS

摘要

FIELD: measurement technology; high-accuracy measurement of phase shift Fo and ratio K of harmonic signal amplitudes in determining frequency characteristics and in correlation analyses. SUBSTANCE: device has first and second input buses, second division unit, control pulse shaper, first retrieval-storage unit, second retrieval-storage unit, adder, unit for square root extraction from sum of squares of two values, first switch, first division unit, trigonometric converter, second switch, comparison unit, first and second output buses with relevant connections. Device provides for high-accuracy measurement of not only phase characteristics of harmonic signals but also amplitude characteristics. EFFECT: enlarged functional capabilities. 5 dwg
