= Time–frequency analysis
{wiki=Time–frequency_analysis}
Time-frequency analysis is a technique used to analyze signals whose frequency content changes over time. It combines elements of both time-domain and frequency-domain analysis to provide a more comprehensive understanding of non-stationary signals, where frequencies and amplitudes vary with time. This is particularly useful in fields such as signal processing, audio analysis, biomedical engineering (like EEG and ECG analysis), and communications.
