- •
Propose an enhanced stochastic resonance (SR) method for weak signal detection.
- •
Proposed FSCSR realizes SR enhancement by full-wave signal construction (FSC).
- •
Full-wave signal construction is realized via Mirror–Cycle–Add operation.
- •
Proposed method is suited to rotating machine fault diagnosis.
- •
Validity and superiority are verified by simulated and practical defective signals.
