### Symmetry and the DTFT

Symmetry and the DTFT. If we know a few things about the symmetry properties of the DTFT, it can make life simpler. First, for a real-valued sequence x(n), the amplitude spectrum (magnitude of the DTFT) is an EVEN function of w . To show this first show that,. Symmetry and the DTFT.
