a hello world example with an analog computer: Euler spiral 🙂

the different wires connect different small computing elements (integrators, inverters, multipliers). knobs allow changing model parameters on the fly. the two output variables are visualized on the xy-plane. pic.twitter.com/2tBC76Fete
ok, imagine you have an oscillation that is not symmetric around 0 (small direct current shift) with some amplitude modulation, for instance with 1/f-dynamics. ➡️ then these 1/f-dynamics will show up in low frequency part of spectrum (red); in addition to around oscillation peak (yellow).
