Abstract

Способ уменьшения погрешностей усилителя постоянного тока с модулятором на входе и демодулятором на выходе, заключающийся в том, что измеряют температуру усилителя и формируют сигнал коррекции, который суммируют с выходным сигналом усилителя, отличающийся тем, что, с целью уменьшения дополнительной погрешности напряжение сигнала коррекции, формируют пропорционально скорости изменения температуры усилителя.A method of reducing errors of a DC amplifier with a modulator at the input and a demodulator at the output, which consists in measuring the temperature of the amplifier and generating a correction signal, which is summed with the output signal of the amplifier, characterized in that, in order to reduce the additional error, the voltage of the correction signal is formed in proportion to the rate of change of the temperature of the amplifier.
