| Feature | Description |
|---|---|
| Low/High Frequency Energy Ratio | Compares the energy content of low-frequency components to high-frequency components within a signal. Useful in applications involving vibration monitoring, acoustic analysis, and fault detection. |
| Low/Mid Frequency Energy Ratio | Analyzes the distribution of energy between lower and mid-frequency bands of a signal, providing valuable insights into the spectral characteristics of audio, vibration, and electrical signals. Typical applications are as follows: • Vibration analysis: identifying mechanical faults or system characteristics in structural dynamics. • Power quality monitoring: detecting and classifying voltage sags and other power disturbances. • Audio processing: distinguishing between different types of audio signals, such as speech and music. |
| Mid/High Frequency Energy Ratio | Analyzes the distribution of energy between mid-range and high-frequency components of a signal, similar to the low/high frequency energy ratio but focused on a different part of the spectrum. Typical applications are as follows: • Vibration anomaly detection (motors, fans, pumps) • Machine health monitoring using accelerometer data • Gesture recognition on IMU sensors (detecting sharp or high-frequency movements) |
