Abstract
Design of minimum-phase FIR-filters are normally done using transformation of a linear-phase FIR-filter. In this paper a new estimation approach is presented. A (minimum) phase is estimated from a squared amplitude response using the theory of complex cepstrums.The amplitude and the estimated phase may then be used to design a FIR-filter optimal in the LS-sense.Two examples are used to verify the method and they indicate a performance as good as the conventional transformation method.
Compared with the transformation method the computation load in the presented method is smaller and it is less sensitive to zeros close to the unit circle.
