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.

Web04. maj 2009. · To make it band pass you need to move its central frequency higher. To do this, multiply h [n] by exp (j*w_offset*n), where w_offset is the amount to shift. If w_offset is positive, then you shift towards higher frequencies. Multiplication in time domain is convolution in frequency domain. Since exp (j*w_offset*n) turns into impulse function ...
