Yeah, that's the way I'd visualise it too.
The way I saw the formula written down is that you take the input wave,
multiply it by different sine and cosine waves, and average. Thinking
about this, I figured that if you have an osciliscope where the
displacement plane rotates instead of translating, you'd get flower
patterns that are off-center only if the frequency you're testing for is
present.
...which appears to be what this guy is saying.
