Abstract

In certain audio and image compression applica- tions, it is necessary to separate the input signal into different frequency components and then encode these components separately. Later, these components may be decoded and recombined to form a reconstruction of the original audio signal or image. Our invention consists of a set of filter bank structures which can be used to separate and recombine these frequency com- ponents efficiently.
