UNCERTAINTY RELATIONS FOR SAMPLED SIGNALS
Abstract
The uncertainty principle for time signals, as defined by Gabor and others, has only been applied to continuous signals and the results cannot be readily extended to sampled signals. An uncertainty product is defined for sampled data signals and an inequality is derived for this product. The class of optimum signals for which the inequality becomes an equality is derived and two examples of non-optimum signals are discussed. (Author)
