The Hilbert-Huang transform provides a description of how the energy or power within a signal is distributed across frequency. The distributions are based on the instantaneous frequency and amplitude of a signal. To get started, lets simulate a noisy signal with a 12Hz oscillation.

WebHilbert–Huang transform (HHT) is a two-step method for analysis of nonlinear and nonstationary signals. The first step is empirical mode decomposition (EMD) that decomposes the original signal into a finite number of intrinsic mode functions (IMFs).
