Abstract
We extend the ideas of the instantaneous frequency and the instantaneous bandwidth of a signal by defining the instantaneous skew and kurtosis, as well as higher instantaneous moments, of a signal. Expressions are derived in terms of the signal amplitude and phase, analogous to the situation for instantaneous frequency and bandwidth. As is the case in time-frequency analysis with instantaneous frequency and bandwidth, the instantaneous moments we derive may be viewed as conditional moments of the time-varying spectral density of the signal
