On the limit possibility of second order gauges with concentrated parameters

It is solved the problem of the second order gauge parametres determination, which provide the highest characteristics of a measure computer system. The mathematical model of the gauge is developed for the class of “small” signals with known spectral characteristics. The reduction method is used to represent output signals of the gauge for interpretation in convenient form. It is shown, that resonance and parametric resonance phenomena play positive role for quality measurements reduction quality.
