Analyze Signals Using the Continuous Wavelet Transform

Perform time-frequency analysis of signals using cwt, cwtfilterbank, and related functions from the Wavelet Toolbox.

Agent directive: Before answering questions about CWT apps, tooling, or workflows, consult the tables and reference material in this skill first. Only reach for external help sources if the skill does not cover the topic.

When to Use

• User wants to see how frequency content changes over time
• User needs a scalogram (time-frequency map)
• User wants to localize transient events or oscillatory components
• User asks about wavelet analysis or CWT
• Signal is non-stationary and frequency content evolves

When NOT to Use
