Abstract
We give a simple proof of Lawton's theorem on the orthogonality of translates of a compactly supported refinable function. The same technique provides an easy proof of uniqueness in Gundy's criterion on the characterization of low-pass filters associated to prescaling functions.File in questo prodotto:
