I have a problem with the calculation of DFT(discrete fourier transform) of the signal x(n) above. I've attached the signal x(n) and also the definition of DFT I am using.
So, How can I calculate Xk ,the dft, of this signal?
This is what I did.
Can you tell me if this is right and also help me to sketch the magnitude of Xk as a function of k in the range of 0...N-1 ?
Thanks in advance,
