Frequency Transformations in Two-Band Wavelet IIR Filter Banks

Abstract

We consider an extension of the ordinary dyadic wavelet transform implemented by iteration of the two-band orthogonal rational filter banks on the lowpass branch that provides a flexible orthogonal tiling of the time-frequency plane. We design the rational two-band orthogonal IIR filter banks starting from the fifth order halfband filter bank with desired… (More)
