Main Question or Discussion Point

Why is the summation for the discrete fourier series from 0 to N-1 (where N is the fundamental period of the signal) wheras it goes from minus infiniti to infiniti for continuous fourier series...


Thank you

Thank you
The summation goes from n=0 to infinity in case of Fourier series in terms of sin(nx) and cos(nx). In terms of einx, it goes from - infinity to infinity.
