## Main Question or Discussion Point

I wanted to remove the dc component from a signal but i can't use the average method because i have only a half cycle sampled not a full cycle . Is there any algorithm or method that can remove the dc component using only a half cycle?

(The signal is sin(x)+2*sin (2x) +3*cos (3x)+4*cos (4x) +5 =f (x), of course normally i dont have the function i have points (x,f (x)) .)
