FIELD: design of A C fast voltmeters, amplitude demodulators, amplitude analyzers. SUBSTANCE: meter incorporates input comparator, two counters, arithmetic unit, noise suppressor, 2AND gate, univibrator and two delay elements. Principle of operation of meter consists in formation of rectangular pulses from measured sinusoidal voltage which duration is determined by moments of crossing of threshold level within limits of single half-wave by examined signal. Duration of pulses generated by specified manner is in strict functional dependence on amplitude of process. EFFECT: simplified design of meter with reduction of analog units. 1 cl, 3 dwg
