Abstract :
The stepdown procedure is an algorithm in which the predictor parameters of a direct form digital filter are converted to the corresponding real reflection coefficients of a digital lattice filter. In this correspondence, a derivation of the stepdown procedure for complex predictor parameters is presented. The complex stepdown procedure is a useful tool for applications ranging from complex filter design to complex predictor coefficient transformations.
