Abstract: In this paper, it is shown that certain Theta functions are
asymptotically optimal for the periodic time frequency uncertainty
principle described by Breitenberger in [2]. These extremal functions
give rise to a periodic multiresolution analysis where corresponding
wavelets also show similar localization properties.
