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

    It’s not even a mixed signal.

      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.

      Maybe he’s just reading the result. The pic didn’t show the open skull and the brain electrodes underneath.

    Both the FFT and this story are anchored on things that are imaginary.

    Have you made it to third order base or is she a bad impedance? Don’t get too hung up on her reluctance or reactance. If she takes no coulombs she is dead inside.

      Interesting, I didn’t know the word reluctance even though magnetic resistance is a familiar concept

    Peak nerd humor, and I love it. Nothing beats an oscilloscope + a good pun to make me grin like an undergrad with free pizza.

    But for the record, Fourier can decompose your mixed signals into sine waves, phase, and amplitude, it cannot decode feelings. Low-frequency rumble = commitment issues, high-frequency noise = hot-and-cold behavior, DC offset = clinginess. Still, blunt instrument number one is a conversation, not an FFT.

    Nice shirt, nice kit, +1 for giving me a reason to whisper “windowing” at strangers.
