Based on insight from three seminal papers by Landau, Pollock and Slepian, which introduce the prolate-spheroidal wave functions as an optimal basis for almost completely capturing the degrees of freedom of a certain class of simultaneously time and band limited functions, we introduce an alternative set of narrow-band functions and discuss how the properties of the optimal prolate-spheroidal basis impose a bound on their number in terms of the time-bandwidth product.Type
