Preface
This chapter is an outgrowth of my course entitled''Introduction to Digital Signal Processing and the Discrete Fourier Transform (DFT)which I have given at the Center for Computer Research in Music and Acoustics (CCRMA) every year for the past 16 years. The course was created primarily as a first course in digital signal processing for entering Music Ph.D. students. As a result, the only prerequisite is a good high-school math background. Calculus exposure is desirable, but not required.
