Title
Relationship between the Wigner-distribution and the Teager energy
Abstract
The link between the Teager energy (TE) operator and the Wigner distribution (WD) is established in this paper. This link results in a simple way to calculate the second conditional moment in frequency of a Wigner distribution. Furthermore, this link helps explain the negative `energy' via the Teager operator, and the negative conditional second moment via the Wigner distribution. We present the similarity between the WD and the time-variant periodogram. Also, we calculate the TE of a time-variant finite-time complex spectrum, and the TE of a time-variant periodogram.
