摘要:
The present invention relates to a system for acquisition of at least one physical variable, in particular for a critical on-board avionics system, comprising a sensor for measuring the physical variable; an acquisition channel receiving an analog signal corresponding to the physical variable measured by the sensor and transforming this analog signal into a corresponding digital signal, at least some of these transformations being able to be carried out with loss of accuracy; self-test unit for checking the integrity of the acquisition channel and generating a self-test result. The system further comprises an analyzer analyzing the self-test result in order to determine an operating mode of the acquisition channel, and for activating the operation of means for correcting the signal delivered by the channel.
