| Abstract English | In this paper, two optimal filter designs for fundamental frequency<br> estimation are presented with the first being based on a filterbank<br> and the second on a single filter. We show that the two designs are<br> related in a simple manner and result in the same residual when used<br> for cancelling out the harmonics. We propose to use this residual<br> for estimating the number of harmonics by combining a noise variance<br> estimate with an order dependent penalty term. This leads to<br> a joint estimator of the fundamental frequency and the order based<br> on the same criterion. Via Monte Carlo simulations, the estimator is<br> demonstrated to have good performance in terms of the percentage<br> of correctly estimated orders. |
