This paper studies signal concentration in the time and frequency domains using the general constrained variational method of Franks. The minimum th moment time-duration measure for band-limited signals is formulated. A complete, orthonormal set of band-limited functions in with the minimum fourth-moment time-duration measure is obtained. Numerical investigations of our optimal 4th moment functions show: 1) less energy concentration in the main lobe than the prolate spheroidal wave functionsdoi:10.1109/tsp.2010.2057427 fatcat:qyffii2bjjdzpicutck4pjttze
