The coefficients of an allpass filter designed to generate doubly complementary filters of order \(N_{1}=9\) are given in Table 13.17.

(a) Plot the phase response of the allpass filter and verify the validity of the specifications described in Equation (13.167).

(b) Compute the difference in phase between \(H_{0}(z)\) and \(H_{1}(z)\) and comment on the results.

(c) Propose the implementation of a QMF filter using the designed filters with minimum number of multiplications per sample.
