WebThe filters in the synthesis bank G 0 (z) and G 1 (z) must be specially adapted to the analysis filters in order to cancel the errors in the analysis bank or to achieve perfect reconstruction. This means that the filter bank is biorthogonal. The synthesis bank, including filters and upsamplers, is the inverse of the analysis bank. WebBiorthogonal analysis filters are not orthogonal to each other but the analysis filters and synthesis filters are orthogonal with respect to each other.
