= Hilbert spectral analysis
{wiki=Hilbert_spectral_analysis}
Hilbert spectral analysis is a technique used primarily in the fields of time series analysis and signal processing to analyze non-linear and non-stationary signals. This method combines the Hilbert transform with the concept of empirical mode decomposition (EMD) to provide a time-frequency representation of a signal. \#\#\# Key Components: 1. **Hilbert Transform**: The Hilbert transform is a mathematical operation that, when applied to a real-valued signal, produces an analytic signal.
