| Jan 7, 2015 at 15:50 | comment | added | got trolled too much this week | As for the "algorithmic methods", any book on filters will teach you the design principles... which you can implement in any software you want. Many books will use MATLAB (which is not free) as the software aid for the calculations. You can translate MATLAB code with almost no changes to GNU Octave (which is free and open-source). | |
