iirpowcomp
Power complementary IIR filter
Description
[
returns the coefficients vectors bp
,ap
] = iirpowcomp(b
,a
)bp
and
ap
, of the power complementary IIR filter g(z) = bp(z) / ap(z),
given the coefficients vectors b
and a
of the
IIR filter h(z) = b
(z)/ a
(z). The vector
b
must be symmetric (Hermitian) or antisymmetric
(antihermitian) and of the same length as the vector a
. The two
power complementary filters satisfy the relation
|H(w)|2 + |G(w)|2 = 1.
