  Fourier?? I hardly know 'er!!

  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.

    It’s a Fourier transform of 1

      Wouldn’t that just be a single vertical line?

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

  That is really useful for finding out whether either of you is on the spectrum

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

    You’re making it complex

  The s/n ratio of these jokes is surprisingly high.

  And now the signals have completely stopped. Science for the win!

  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.

    WDYM you’re not just going with sine waves vibes

  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
