Solutions to the non-linear differential equation x ″ + 0.25x ′ + x(x² – 1) = 0.3 cos t are chaotic. It’s more common to see plots of chaotic systems in the time domain, so I wanted to write a post looking at the power spectrum in the frequency domain. The following plot was created by solving […]The post Chaos in the frequency domain first appeared on John D. Cook.
