That's not a fourier transform, that's just a scope with a sine wave.

It's not even a mixed signal.

It's a Fourier transform of 1

Wouldn't that just be a single vertical line?

Hence why I formated my comment as a question ;)

It's one of the sine waves making up the mixed signal and he's got its frequency and amplitude, which is what fourier analysis is about.
