Abstract
The authors demonstrate that given a function orthogonal with respect to shifts of integer multiples of a constant Δ, its bandwidth is related to the shift parameter Δ. This result is used to establish an upper bound on the density of the independent states in the time-frequency plane for scaling functions and wavelets
