- In the next example, we also see that the phase offset of a real-valued sinusoid is ambiguous unless a reference (sin or cos) is specified. is unambiguously defined.
- Example 2:
In both examples the local maxima of correspond to for integer values of N. This has applications in the field of computer vision.
