%X Cosine Modulated Filter(CMF) bank is a kind of broadly used filter bank. By proving the equivalence of the Perfect Reconstruction(PR) conditions of time-analysis and frequency-analysis, the inherent relationship between Time Domain Aliasing Cancellation(TDAC) and CMF is found. By the means, the useful results of the two methods can be conveniently. Finally, a new kind of nonuniform filter bank is built based on TDAC which can be easily modified to audio coding in accord with psychoacoustics.
