Abstract
A systematic procedure for estimation of the transformation length
in linear- to minimum-phase FIR-filter transformation using
complex cepstrums is presented in this paper. The basis of the
method is an introduced disturbing function. This function
describes how aliasing affects the final frequency response of the
minimum-phase FIR-filter. The transformation length estimation is
made using the absolute value of the dominating zero in the
linear-phase FIR-filter and the maximum allowed amplitude and
phase deviation of the disturbing function. Two examples are
given. The first one verifies the introduction of the disturbing
function while the second example uses the proposed procedure to
estimate the necessary transformation length for a linear-phase
lowpass filter.
