FIELD: automatic control for correcting devices of measuring- instrument servo systems. SUBSTANCE: device has differential amplifier, analog memory location 6 whose output is connected through resistor 7 to inverting input of differential amplifier, capacitor 8 inserted in feedback circuit of differential amplifier, additional capacitor 10 inserted between noninverting input of differential amplifier and common minus bus. Input voltage supply 1 is connected to inputs of switches 2 and 3, output of clock generator 4, to input of NOR gate 5 whose inversion output is connected to control input of switch 2 whose output is connected to input of analog memory location 6 and direct output, to control input of memory location 6 and at the same time to switch 3 whose output is connected through additional resistor 9 to inverting input of differential amplifier. EFFECT: enhanced precision due to eliminating stray components in output signal. 1 cl, 1 dwg |
