Signal Quality (+2)

Signal Quality

1. Check sampling rate - Ensure Nyquist criterion for frequencies of interest
2. Remove transients - Skip build-up periods in OrcaFlex simulations
3. Validate stationarity - Use multiple segments for PSD estimation
4. Handle gaps - Interpolate or segment around missing data

Rainflow Analysis

1. Hysteresis filtering - Remove small cycles (typically < 1-5% of range)
2. Residual handling - Choose appropriate method for incomplete cycles
3. Cycle binning - Use consistent bin sizes for histogram comparison
4. S-N curve matching - Ensure stress units match S-N curve units

Performance Optimization

1. Parallel processing - Use batch extraction for multiple files
2. Memory management - Process long signals in chunks
3. Downsampling - Reduce sampling rate if high frequencies not needed
4. Result caching - Store intermediate results for reprocessing
