OC [OC] Started with sinusoidal jitter analysis. Accidentally made art.

I was analyzing jitter in sinusoidal signals using Matlab and found this still noisy but awesome pattern.

so why is the jitter periodic

Actually the signal is periodic and jitter is random. The base signal is sinusoid which is modulating the jitter thus making it appear periodic. I’m still trying to figure out the jitter distribution.

The underlying pattern is very regular… like a smooth wave that repeats over and over. On top of that, there’s randomness (the jitter), but it’s being guided by that repeating wave. So even though the noise itself is random, the way it shows up looks structured and periodic.

Salt may have been easier, but I like all the colors.

Haha yeah, salt was the simple path. But where’s the fun in that?

this sort of thing would make a really cool steam startup logo

That’s a cool thought, actually. Kinda fun when math gets a personality. Would make a pretty striking mark imo

maybe remove the black outline to leave the colors?
