Abstract :
In this paper, a new procedure for constrained digital signal smoothing is presented. It is based on least-squares approximation of functions defined on an equidistant set of points by orthogonal polynomials. The digital signal smoothing is described by linear operators represented by circulant Toeplitz matrices with integer coefficients which can be efficiently realized
