Q1
Let x(t) be a periodical function with complex Fourier
Coefficients given as
Cn 
1
sinc(n/2)
2
Using Matlab Construct and plot the approximate
periodical function x(t) using the partial sum , for N = 5 ,
15, 100

N
x(t ) 
Cn e jn0t
n  N
Use the time interval from t= 0 to t=8 increment of 0.01
Note : Matlab does not have zero or negative index for
matrix or vector
