Abstract
Previous work uses Adaptive Notch Filters (ANF) to track time-varying signals in time-frequency plane with a fixed number of ANFs. However, if too few ANFs are used, some important components may be missed. On the other hand, if too many ANFs are used, noise is also tracked and some artifacts may be introduced. This paper summary proposes an approach to estimate a number of ANFs in order to track a specific time-varying signal.
