title: "Understanding instantaneous frequency detection: a discussion of Hilbert–Huang Transform versus Wavelet Transform"
description: A head-to-head between the Hilbert–Huang transform and discrete wavelet decomposition for instantaneous frequency in non-stationary signals. Tests on synthetic data and real EEG recordings show HHT yielding more interpretable oscillatory components.
