| Sep 27, 2018 at 22:10 | comment | added | aneps | @MaximilianMatthé, I want to filter out all the frequencies above 80 Hz from my signal. In this case what is N_clear? How should I modify the code to filter out all the higher frequencies? Thank you. | |

That's perfect, but what do you mean with N_clear? If I want to delete frequency components below 1Hz, knowing that f=k*fs/N, with a given sampling frequency, N the length of the signal and k a vector of the length of the signal, I should delete every component k that is under 1Hz from the S vector? Thanks for the answer! @maximilian-matthé
