Abstract :
This paper proposes a new approach-fixed-levels least squares (FLLS) method for linear-phase FIR filter design. It is mainly directed towards rejection of Gibbs phenomenon through introduction of a set of equally spaced fixed levels in transition band and subsequent redefinition of the approximated and weight functions. Detailed mathematical solution of the problem as well as a numerical example are given. The results in graphical form are shown as an output of FLLS software model
