The Fourier Transform is a tool that breaks a waveform (a function or signal) into an alternate representation, characterized by sine and cosines. The Fourier Transform shows that any waveform can be re-written as the sum of sinusoidal functions. This book presents an introduction to the principles of the fast Fourier transform. The book covers topics of FFTs, frequency domain filtering, and applications to video and audio signal processing. This authoritative book provides comprehensive coverage of practical Fourier analysis.
