Abstract :
A generalized lapped orthonormal transform (GLOT) formulation is presented for the analysis and synthesis of signals. This formulation is composed of a variable width window and a linear combination of weighted orthonormal functions. Tradeoffs in the specification of windows are examined. A sinusoidal example is considered, and a fast algorithm is provided for its evaluation
