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

This is derivative af

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

[-] Aceticon@lemmy.dbzer0.com 3 points 4 weeks ago

Wouldn't that just be a single vertical line?

He didn't say 1 of which unit or function

[-] Aceticon@lemmy.dbzer0.com 2 points 4 weeks ago

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.

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

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

[-] aeronmelon@lemmy.world 13 points 4 weeks ago

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

[-] Natanael@infosec.pub 1 points 4 weeks ago

The friend she said you shouldn't worry about gave her a band pass

[-] j4k3@lemmy.world 11 points 4 weeks ago

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.

[-] lauha@lemmy.world 3 points 4 weeks ago

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

[-] pHr34kY@lemmy.world 9 points 4 weeks ago

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

[-] Natanael@infosec.pub 7 points 4 weeks ago

You're making it complex

[-] expatriado@lemmy.world 9 points 4 weeks ago

DSP gave me PTSD

[-] abcdqfr@lemmy.world 3 points 4 weeks ago

Fourier than what?

[-] sheepishly@fedia.io 3 points 4 weeks ago

Fourier?? I hardly know 'er!!
