Paper Abstract

The question of what the joint and conditional time-frequency moments are in terms of the signal and spectral amplitudes and phases is considered. From these moments, a time- frequency density can be constructed using the method of maximum entropy. This technique is used to assess the plausibility of expressions recently derived for low-order conditional and joint moments.ALso investigate is whether or not there is a lower bound on the local time- bandwidth product of a time-frequency density, as there is for the global case.
