The Hilbert spectrum is a tool used in signal processing and time series analysis that provides a way to analyze non-linear and non-stationary signals. It is derived from the Hilbert transform, which can be applied to a signal to create an analytic representation. The Hilbert transform allows the extraction of instantaneous frequency and amplitude from a signal, creating a time-dependent representation that can reveal information about the signal's frequency content over time.
