METHOD FOR REDUCING ERRORS OF DIRECT CURRENT AMPLIFIER WITH MODULATOR AT INPUT AND DEMODULATOR AT OUTPUT |
| 摘要 |
FIELD: measurement equipment.SUBSTANCE: method for reducing errors of a direct current amplifier with a modulator at the input and a demodulator at the output consists in the fact that temperature of the amplifier is measured and a correction signal is shaped, which is added to an output signal of the amplifier; with that, voltage of the correction signal is formed pro rate to the speed of the change of amplifier temperature.EFFECT: compensation of amplifier temperature error.1 dwg |
