While the full copyrighted textbook is rarely hosted legally for free, T.W. Körner (a professor at the University of Cambridge) has published supplementary notes, exercise solutions, and related lecture PDFs on his official university faculty page. These free resources are invaluable companions to the text.

Academics and self-learners frequently search for a for several distinct reasons:
This is the core of the book.
Transitioning from periodic functions to non-periodic functions, Körner introduces the continuous Fourier transform. This section explores the profound symmetry between a function and its transform, detailing the inversion formula, Plancherel's theorem, and the operational calculus that simplifies differential equations into algebraic ones.

He is not afraid to tell you that a proof is "ugly" or that a historical figure was "stubborn." This narrative style makes the book readable in a way that few advanced math texts are. He guides the reader through the thicket of Lebesgue integrals and $L^p$ spaces with a narrative thread that keeps you turning pages.
Most mathematical texts operate on a "definition-theorem-proof" loop. While rigorous, this often strips the subject of its historical context and practical motivation. Thomas William Körner takes a different approach.
The book is structured to guide the reader through the core concepts of Fourier analysis while constantly revealing its broader implications. An early glimpse into its contents illustrates the breadth of topics covered. Chapters guide the reader from the foundational theory of Fourier series, through their use in solving differential equations and orthogonal series, to the powerful concept of Fourier transforms. The final chapters explore more advanced territory with discussions on "Further developments" and "Other directions", demonstrating that Fourier analysis is a vibrant and evolving field.
