<p><b>Abstract</b>—Scale-space filtering is the only known method which provides a hierarchic signal description method by extracting features across a continuum of scales. One of its important characteristics is that it demands the filtering involved does not create generic features as the scale increases. It has been shown in [<ref rid="bibi03094" type="bib">4</ref>], [<ref rid="bibi03095" type="bib">5</ref>], [<ref rid="bibi03096" type="bib">6</ref>] that the Gaussian filter is unique in holding this remarkable property. This is in essence the so-called scaling theorem. In this paper, we propose two scaling theorems for band-limited signals. They are applicable to a broader class of signals and a bigger family of filtering kernels than in [<ref rid="bibi03094" type="bib">4</ref>], [<ref rid="bibi03095" type="bib">5</ref>],[<ref rid="bibi03096" type="bib">6</ref>]. An in-depth discussion of our theorems and the previously published ones is also given.</p>
