Open publisher page 1 citations

Abstract

The performances comparing the results of using plain gradient algorithm (PG) in a second-order adaptive IIR lattice notch filter (PG/spl I.bar/L) and adaptive IIR notch filter with constrained poles and zeros (PG/spl I.bar/C) are clearly presented here. It is shown that the PG/spl I.bar/L yields the performances over the PG/spl I.bar/C. Computer simulations are provided to confirm the performances of PG/spl I.bar/L.
