  • Abstract
    It is well known that FIR (finite impulse response) filter banks which satisfy the perfect reconstruction (PR) property can be obtained by cosine modulation of a linear-phase prototype filter of length N =2mM, where M is the number of channels. Moreover, the overall delay of this system is (2mM-1) samples. The author presents a PR cosine-modulated filter bank in which its overall delay is (2(α+1)M-1) samples, where α is a positive integer in the range 0⩽α⩽2m-2. Consequently, as is shown, the prototype filter of the proposed filter bank no longer has linear phase
