Abstract:
A method for compensation of phase delays that occur in discrete sampling of an analog output signal (US), comprising the steps of subjecting the output signal (US) to signal processing by an anti-aliasing filter and then by a sampling member to obtain a sampling signal (UA) that has a sampling period (T); compensating a phase delay of the sampling signal caused by the sampling member; taking into account the sampling signal of a preceding sampling period to obtain a signal (UF,K); and compensating the phase delay of the sampling signal caused by the anti-aliasing filter, taking into account a filter time constant (TF) of the anti-aliasing filter, a sampling period (TA) of the sampling member, and the sampling signal of the preceding sampling period, to obtain a signal (USK).
