- •
Load changes and valve faults show different patterns in the spectrogram.
- •
Autocorrelation of the spectrogram difference emphasizes these patterns.
- •
Distinctive features can be extracted from autocorrelation representation.
- •
Classification works well for arbitrary load levels of the compressor.
