Abstract

nominal input signal of amplifier A2. Then s ! 0.5.10-3%. The drift of the Input current of the amplifier and the leakage current of the commutator is 0.5.10 -~~ A/~ which results in additional temperature error. When the temperature varies by 10~ the error ATt ! 0.5. I0-~%. Errors of Input Amplifier Af. The relative errors due to instability of the feedback resistances of amplifier A2 may be ignored, since in the ADC there are no limitations of the stability of the transmission coefficient of amplifier A2, because the measured voltage U x and the reference voltage Uo are fed to the same input. It is known that the gain Kfb affects the attenuation factor of the in-phase signal Mip
