What It Is

CWRU bearing vibration, ball fault. Drive-end accelerometer at 48 kHz with a 0.014 in diameter ball-element defect.

Interpretation

Standard analysis sees: red spectrum (low-frequency / 1-over-f power). The atlas finds no named structure, but the source is distinctively extreme on AutoRegressive:ar_coef_2 (-5.5z) — beyond what the standard bank predicts for it. It sits beside EEG Seizure in the atlas (standard-bank rank 28) — a neighbor conventional features miss.
