WebThe continuous wavelet transform (CWT) is a time-frequency transform, which is ideal for analyzing nonstationary signals. A signal being nonstationary means that its frequency-domain representation changes over time. Many signals are nonstationary, such as electrocardiograms, audio signals, earthquake data, and climate data.
