Noise Sensitivity of Teager-Kaiser Energy Operators and Their Ratios
Pradeep Kr. Banerjee, Nirmal B. Chakrabarti
The Teager-Kaiser energy operator (TKO) belongs to a class of autocorrelators and their linear combination that can track the instantaneous energy of a nonstationary sinusoidal sig…

A representation of non-uniformly sampled deterministic and random signals and their reconstruction using sample values and derivatives
Nirmal B. Chakrabarti
Shannon in his 1949 paper suggested the use of derivatives to increase the W*T product of the sampled signal. Use of derivatives enables improved reconstruction particularly in the…
