A New Approach for Estimation of Instantaneous Mean Frequency of a Time-Varying Signal

A New Approach for Estimation of Instantaneous Mean Frequency of a Time-Varying Signal

<p/> <p>Analysis of nonstationary signals is a challenging task. True nonstationary signal analysis involves monitoring the frequency changes of the signal over time (i.e., monitoring the instantaneous frequency (IF) changes). The IF of a signal is traditionally obtained by taking the fi...
