Analytic techniques are presented which employ orthogonal polynomials in the design of linear phase non-recursive digital filters. Pass-band and stop-band transformations are derived to approximate an ideal low-pass filter by specifying permissible ripples and order. Filters obtained using linear programming techniques are compared with filters presented in this paper.
