A periodic signal x(t) with a fundamental period of 2 seconds is described over one fundamental period by
x(t) = sin(2*pi*t) for t< 0.5
0 for 0.5 < |t| < 1
Graph the signal. Then graph on the same scale the signal Xn(t) given by
Xn(t) = Summation Cx[k]e^(j2*pi*kt/To) where k is -N to N
For N=10,20 and 30 ( In each case the time scale of the graph should cover at least two fundamental periods of the original signal).
Plz help i am beginner and confused :'(

I think you will find some good help by going to the MATLAB Plot Gallery, taking a look at some of those examples, and then adapting the code available there to your case.
