Sure, treat it like a puzzle. First isolate the noise: run a low‑pass filter to remove high‑frequency junk, then use a Fast Fourier Transform to spot repeating frequencies. If it looks like a fractal, look for self‑similarity across scales—zoom in and see if the pattern repeats. Finally, run a statistical test (like chi‑square) to see if the pattern is significant or just random. If it passes, you have a likely hidden signal.
