"Brno" . . "A quadrature mirror filter banks are the most frequently realized by FIR filters. The input signal is decomposed into some frequency subbands by these filters. In the case of dual channel filter banks this subbands are two. A subbands coding can be done in individual subbands. By this process the subbands signals are distorted. This distortion gets into reconstructed output signal. In the case of replacement FIR filters in decomposition section by sigma-delta modulators a new structure may be designed, which is more resistant to this type of distortion." . "Brno" . . . . .
