@article{Kumar1990TrackingOB, title={Tracking of bandpass signals using center-frequency adaptive filters}, author={Ratnam V. Raja Kumar and R. Pal}, journal={IEEE Trans. Acoust. Speech Signal Process.}, year={1990}, volume={38}, pages={1710-1721} }

A class of constrained adaptive filters, called recursive center-frequency adaptive filters, is applied to the tracking of bandpass signals. For this application, these filters form a class of completely digital tracking filters which are shown to have several advantages over existing analog and semidigital tracking filters. A procedure of analyzing the tracking behavior of these filters using the ordinary differential equation approach is presented. The tracking performance of two examples of… Expand
