Shifting and phase difference Assume we have a series v[k] of length M=16. It's shifted to the right in a circular manner by k0=2 samples. 

Which phase difference between the DFT spectrum of the original signal and that of the shifted version is to be expected?
The phase shift will be a factor of $e^{j2\pi k_0 m/M}$, where $m$ is the DFT bin number
