Abstract
In a recent paper, Larkin [1996] proposed a new structure for efficient demodulation of AM signals. This structure was based on the Teager-Kaiser energy operator. In this paper, we present a study of a particular sampling frequency used in Larkin´s approach. We have studied the performance of the energy operator using such a sampling frequency. In particular, we have shown that the upper bound of demodulation error is proportional to the square of the sampling period. The performance of the energy operator using a non-ideal sampling frequency is also studied. In addition, we present a new interpretation of Larkin´s approach and compare its performance with that of the energy operator
