Hi all..
I have currently taken a project on fourier analysis from a professor of
Unfortunately he was very vague about what I have to do.
He just said that I would take a function(periodic) add noise,and then
apply a low pass filter on it to eliminate the noise.The problem is I dont
have a clue about what a low-pass filter is,and he insisted that I should
find it alone..anyway,if anyone has ann appropriate example,I would be
glad if he sent it to me
