Abstract :
This paper describes a method to approximate the impulse response of a linear shift-variant system by the impulse responses of a set of linear shift-invariant systems which process in parallel on various windowed versions of the input signal. The method is outlined for one-dimensional systems but the extension to multidimensional case is straightforward.
