Fourier transform
The Fourier transform is a mathematical operation that transforms a time-domain signal into its constituent frequencies, providing a frequency-domain representation. It is a fundamental tool in signal processing, physics, and engineering, allowing for the analysis and manipulation of signals in various applications.

Key Point
Understanding wavelet transforms opens up a new dimension in signal processing, allowing for both time and frequency analysis simultaneously. This duality enhances the ability to capture transient features in data that traditional methods may overlook.
Lesson
Key Point
Wavelet transforms are mathematical tools that decompose signals into components at various scales, providing both time and frequency information, unlike Fourier transforms which only offer frequency insights. This makes wavelet transforms particularly useful for analyzing non-stationary signals, where the frequency content changes over time.
