Abstract
Owing to limitations on the convergence coefficient placed by time delays in the cancellation path, fast rates of algorithm adaptation may yield poorer performance than slow rates in active control implementations. This is shown experimentally for the performance criteria of error minimization, speed of convergence, and excitation of unreferenced signal components
