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.
