Abstract :
In previous papers it has been demonstrated that a class of digital filter structures derived from the theory of orthogonal polynomials has practical utility in digital signal processing problems. In this paper the specific algorithms necessary to synthesize and scale these structures in fixed-point arithmetic (based upon L2norm scaling) are presented and implemented as Fortran programs.
