Time-Frequency Analysis

Time-frequency analysis is a method used to analyze signals that change over time, such as sound waves or financial data. It combines time and frequency information to show how different frequencies are present in a signal at various times. This is useful in many fields, from music and audio processing to neuroscience and telecommunications, because it helps capture dynamic behaviors that traditional analysis might overlook. By visualizing this information, one can understand patterns and trends that evolve, providing deeper insights into the underlying processes.
