Popis:	Design of quadrature mirror filter banks based on all-pass filters in the least-squares sense can be reduced to solve a set of linear equations associated with desired phases. This paper proposes explicit formula for Toeplitz and Hankel matrices that required in solving the set of linear equations such that the filter coefficients can be derived by using efficient algorithm.
