load_signal
Load a machine vibration signal into memory, making it available by ID for efficient repeated use in vibration analysis and fault detection tools.
Instructions
Load a signal into the in-memory repository for fast repeated access.
Once loaded, reference the signal by its signal_id in other tools like
compute_power_spectral_density, diagnose_vibration, etc.
Args:
filepath: Filename relative to data/signals/, or absolute path.
signal_id: Custom ID (defaults to filename stem).
sampling_rate: Sampling rate in Hz (overrides metadata file).
