Abstract :
We develop a method to detrend the phases of measured multisine signals. We find a time reference that removes the linear component of the measured phases and aligns them, within a precision specified by the user, to their expected values. An initial guess is provided by a closed-form expression. We then find the global minimum of a user-specified error function. The simple postprocessing algorithm is general and can be implemented in many software packages.
