TIME-DOMAIN FILTER BANK ANALYSIS - A NEW DESIGN THEORY

This paper presents a new time-domain approach for the analysis and design of a broad class of general analysis/synthesis systems based on M-band filter banks. The paper derives a set of time-domain conditions for reconstruction which can be used directly in a filter bank design procedure. The general and unrestricted nature of this framework allows for the design of many useful banks. In addition to the complete derivation of the time-domain conditions, the paper also describes the associated filter bank design procedure and a number of design examples are included.
