Abstract An efficient iterative lagrange multiplier approach is proposed for the design two-channel low delay perfect reconstruction filter banks. This approach has high design efficiency and can be used to design both equal-length and unequal-length filter banks. A design example is presented and compared with other methods. It can be shown that two-channel perfect reconstruction linear phase filter banks with higher stopband attenuation can be obtained using the new method.
