Properties of Discrete Fourier Transform

As a special case of general Fourier transform, the discrete time transform shares all properties (and their proofs) of the Fourier transform discussed above, except now some of these properties may take different forms. In the following, we always assume ${\cal F}[x[m]]=X(e^{j\omega})$ and ${\cal F}[y[m]]=Y(e^{j\omega})$.
