Recommended books/links for Fourier Transform beginners? I am a student taking engineering course and wish to learn more about Fourier Transforms. It seems very useful. Would highly appreciate it if anyone could advise me where to start.
 A: I first learned Fourier techniques from Bracewell's The Fourier Transform and Its Applications, but I'm digging the non-conventional treatment in Meikle's A New Twist to Fourier Transforms.
A: For a general engineering perspective, Erwin Kreyszig's  book "Advanced Engineering Mathematics" would have some chapters on Fourier and other integral transforms.
For a more mathematical approach, but still with applications in mind, Sneddon's book Fourier Transforms is recommended. It has a lot of physics applications.
The book of Taub and Schilling on Principles of Communication Systems is very good from an electrical engineering point of view. I particularly liked this last book.
A: This link is really, really good!

A: If you have an interest in engineering optics or linear systems, try Gaskill's book.  It's good to start from.
David Kammler's book is also a a good introduction.  The first part explains the connections between Fourier Series, Fourier Transform, DTFT, DFT very clearly which other books often gloss over.
