WebWhich, in a few phrases, is explained as follows: Draw a square pulse in the frequency domain that starts from DC (0 Hz) and stops at the cut-off frequency of your low pass filter. Do an inverse DFT of that and this results to a sinc pulse. Use that sinc to filter your data. The longer the sinc, the sharper the cut off.
