| Jan 25, 2014 at 21:30 | comment | added | sellibitze | IF you don't already know the impulse response you want your signal convolved with then "filter design" is the topic you should research. try "windowed sinc" or use a tool like Gnu/Octave which comes with various nice functions for designing these things. Apart from the "windowed since" approach most of the others are kind of a black art and many people just rely on tools to compute the coefficients for them. | |
