5.1: Introduction to Fourier Analysis
This page discusses Fourier's 1807 proposition that periodic signals can be represented as combinations of sinusoidal waves. Despite early skepticism about his theory's convergence, Fourier analysis is now essential for signal and system analysis, as sinusoids serve as Eigenfunctions in linear, time-invariant systems.
