Written in conversational style, this book will help you comprehend the Fourier analysis and its myriad forms, such as DFT, DTFT, CTFT etc. as never before. Our goal in this book is to help you develop an intuitive understanding of what is happening when you do a FFT of a random signal. There is a long story behind this apparently easy-to-compute yet hard-to-understand concept.
