Abstract of Lecture
 
In this talk, we present a new piloted method for extracting information on the distance between the frequency of the input sinusoid and the zero of the notch. It uses three (or more) notches, namely, a main notch and two (or more) pilot notches implemented with minimal additional cost. The pilot notches are used to analyze the gradient estimates at the same sampling instance but at several frequency points as the main notch. Simulation results show that the piloted notch technique is significantly superior to step-size determination based on gradient estimates at several sampling instances. The piloted method can be used in conjunction with most existing algorithms to determine the step size.
