Abstract
A new phase correction method by means of digital all- pass filters is presented. Unlike most of the delay correction techniques described in the literature, it starts from phase data which may be corrupted with (measurement) noise. Due to an appropriate choice of the model the phase intercept distortion is avoided. Some practical ex- amples and experimental results are given.Keywords
