Harmonic analysis delves into representing functions as sums of sinusoidal waves, using tools like Fourier series and transforms. Originating from Fourier's 18th-century work, it's crucial in engineering, quantum physics, and data science for analyzing signal patterns. This field encompasses applied, computational, and abstract branches, each with unique applications in various domains such as music composition, electrical engineering, and image processing.
