Time-Frequency Analysis in MATLAB

Analyze how frequency content evolves over time using STFT, CWT, synchrosqueezing, reassignment, cross-signal methods, and data-adaptive decomposition.

Agent directive: Consult the reference guides in references/ before answering. Each guide covers a specific domain with syntax, gotchas, and common mistakes.

When To Use

• Analyzing how frequency content evolves over time (spectrogram, scalogram)
• Choosing between STFT, CWT, synchrosqueezing, reassignment, or EMD/VMD
• Extracting and reconstructing individual signal components from a TF representation
• Computing time-varying coherence or cross-spectrum between two signals
• Decomposing signals into additive time-domain components (wavelet MRA, EMD, VMD)
• Estimating instantaneous frequency or Hilbert spectrum
