Abstract
The EKT method is a recent extraction technique of periodic signals from noise. It is a method presenting a great practical interest because of its easy realization and its high signal-to-noise ratio (SNR)—higher than that of the averaging method. However, it is only valid for signals of known period. Since in practice, periods are not always known with good precision, the EKT method remains limited. To enlarge its application field, we propose in this paper an adaptive EKT method, which could be applied to signals whose variation interval of the fundamental frequency is known.
