Hello all, I'm a third year university physics major. I haven't read much on Fourier analysis however I have had been introduced to it through an oscillations and waves class. My professor was saying that it can be applied to many different areas and is extremely helpful tool to have under your belt for many reasons. Since I have been introduced to Fourier integrals and transforms and what they mean in terms of oscillations, I am seeking an introductory to slightly advanced text to buy on the topic. Could anyone recommend a specific text for Fourier analysis that applies it to many areas, such as physics, business, etc? More or less looking to get a good summer reader, so I can keep the brain cells working. Any other suggestions on books that are worth reading (not only On Fourier analysis) that will help me out in the future would be taken into account too! Thanks!
