Abstract
A signal measurement and processing device includes two systems allowing a signal and its opposite to be simultaneously received at the input and two signals able to take polynomial form, as a function of the input signals, to be returned. The device includes means for performing a weighted sum and difference of the two output signals in such a manner that at least the weighted sum is independent to a first order of the variations in the input signals. This processing operation is particularly well adapted to systems subjected to spurious effects such as thermal drifts.
