  • Abstract
    A method of applying error feedback in three digital ladder and lattice filter structures derived from the theory of orthogonal polynomials is proposed. It is shown that error feedback leads to significant improvement in both the roundoff noise characteristics and limit cycle behavior. In particular, the error-compensated one-multiplier structure is superior to the (uncompensated) normalized ladder. This results in significant savings in both hardware and Speed of implementation.
