This file designs two stage Nyquist filters with a given rolloff and desired ripples of Dc and Ds. The design aims to find the lowet number of multipliers. The main file is called Design_Double.m The matlab script is based on the design method in the following article: A. Eghbali, T. Saramä ki, and H. Johansson, "On two-stage Nyquist pulse shaping filters," IEEE Trans. Signal Processing, vol. 60, no. 1, pp. 483-488, Jan. 2012. Please cite the above article if you use this file. In case o
