Abstract

Digital filter sharpening aims to improve filtering by cascading structures employing multiple use of an original prototype's unchanged coefficient set. Starting with a visitor-designed FIR prototype, we demonstrate the operation of three different sharpening methods, comparing their various advantages and shortcomings. Two tools are employed: a Simulink model, facilitating visual examination of virtual instrument displays, and a MATLAB package that provides a compact equivalent filter model of the sharpened resultant.
