Hello all
I have the following problem.
I have to calculate the DTFT of this : x(n)=u(n)-u(n-4).
So far , from what I have studied I have understood, that DTFT , is actually many DFT's calculated for different omega values lets say in an interval from -pi to pi , with step 0.2 .
Is this so far correct ?
we know that (it is proven) x(n) = 1
So finally have this:
Now my main problem, how can I continue from that step ? Am I supposed to get some arithmetic result ?
Thanks for you help !
