Meant to serve an "entertaining textbook," this book belongs to a rare genre. It is written for all students and practitioners who deal with Fourier transformation. Fourier series as well as continuous and discrete Fourier transformation are covered, and particular emphasis is placed on window functions. Many illustrations and easy-to-solve exercises make the book especially accessible, and its humorous style will add to the pleasure of learning from it.
From the reviews: "This short book is about single-variable Fourier series and transforms with a total emphasis on signal processing ... . Each chapter ends with a number of exercises (solutions are at the end of the book). Students with the persistence to finish the exercises without looking at the answers will have learned a lot ... . The book's ... focus is unusual and may be a reason for the success of the German editions." (Colin C. Graham, Mathematical Reviews, Issue 2006 k)
