#### Normalized DFT Power Theorem

Note that the power theorem would be more elegant if the DFT were
defined as the coefficient of projection onto the *normalized DFT sinusoids*

*normalized DFT*(§6.10), the power theorem becomes simply

*geometrically*, as in Chapter 5, then this result is expected, because and are merely coordinates of the same geometric object (a signal) relative to two different sets of basis signals (the shifted impulses and the normalized DFT sinusoids).
