Abstract :
The authors build on Cohen´s work on instantaneous bandwidth and frequency by extending it to a multi-window framework. Unlike the case with a single spectrogram, the multi-window framework allows one to obtain a time-varying spectral estimate that simultaneously satisfies instantaneous bandwidth and frequency constraints.
