DEVICE TO MEASURE ROOT-MEAN-SQUARE VALUE OF VOLTAGE Russian patent published in 1995 - IPC

Abstract SU 1566913 A2

FIELD: instrumentation. SUBSTANCE: device to measure root-mean-square value of voltage has amplifier 2, filter unit 3, controlled amplifier 4, detector 6 of root-mean-square value, counter 7, indicator, 8, resistive divider 9, comparators 11 and 12, univibrators 13 and 14, analog multiplexer 15, logic elements 16, 17, 19. Insertion of analog keys 25 and 26 provides for time reduction of transition processes by factor of 10² which allows processing of measured signals to be conducted in real time. EFFECT: increased speed of response of device. 2 dwg
