Abstract :
In practice all signals are time-limited and thus have infinite bandwidth. Bounds and effective bandwidths of 2D functions are derived for the maximum error criterion. The 2D functions considered are circular symmetric and of compact support, and their nth derivatives are of bounded variation, where n>or=2. The low-pass filter used for truncation is also circular symmetric.<>
