Frequency Analysis Part I
Fourier Decomposition
Pascal Wallisch
This chapter introduces the most common method of decomposing a time series into frequency components, Fourier analysis. You will learn about the Fourier transform and the associated amplitude and phase spectra. The MATLAB® implementation of the fast Fourier transform (FFT), an efficient algorithm for calculating Fourier transformations, will be introduced and applied to the analysis of human speech sounds.
