Time-frequency localisation operators-a geometric phase space approach: II. The use of dilations

Published

Journal Article

Operators which localise both in time and frequency are constructed. They restrict to a finite time interval and cut off low as well as high frequencies (band-pass filters). Explicit expressions for eigenvalues and eigenfunctions (Laguerre functions) are given.
