FIELD: measurement technology.
SUBSTANCE: meter can be used for producing high-speed ac voltmeters, amplitude demodulators, amplitude analyzers etc. Principle of operation of meter is based on forming square-shaped pulses from measured sinusoidal voltage by means of comparator. Duration of pulses are determined by moments when sinusoidal pulses cross threshold level within limits of one half-wave. Amplitude of tested sinusoidal voltage is determined by number of pulses, total duration of pulses and pulse repletion period in functional converter.
EFFECT: improved precision of measurement.
