The Hilbert spectrum (sometimes referred to as the Hilbert amplitude spectrum), named after David Hilbert, is a statistical tool that can help in distinguishing among a mixture of moving signals. The spectrum itself is decomposed into its component sources using independent component analysis. The separation … See more The Hilbert spectrum is computed by way of a 2-step process consisting of: • Preprocessing a signal separate it into intrinsic mode functions using a mathematical decomposition such as singular value decomposition See more The Hilbert spectrum has many practical applications.
