Abstract

In this paper we study the time-frequency localization properties of biorthogonal modulated filter banks. The localization of the prototype filter is computed using two different measures. Design examples are presented showing that the lower bound of the uncertainty relation can be nearly reached. We also show that biorthogonal filter banks offer attractive trade-offs between reconstruction delay and time-frequency localization, not allowed when using orthogonal ones.
