From the reviews of the first edition:
"This lovely book is intended as a primer in harmonic analysis at the undergraduate level. All the central concepts of harmonic analysis are introduced using Riemann integral and metric spaces only. The exercises at the end of each chapter are interesting and challenging; no solutions are given. …"
Sanjiv Kumar Gupta for MathSciNet
"… In this well-written textbook the central concepts of Harmonic Analysis are explained in an enjoyable way, while using very little technical background. Quite surprisingly this approach works. It is not an exaggeration that each undergraduate student interested in and each professor teaching Harmonic Analysis will benefit from the streamlined and direct approach of this book."
Ferenc Móricz for Acta Scientiarum Mathematicarum
From the reviews of the second edition:
"This is the second edition of a beautiful introduction to harmonic analysis accessible to undergraduates. … The first part deals with classical Fourier analysis, the second provides the extension to locally compact abelian groups, and the third part is concerned with noncommutative groups."
