Abstract:

The fast Fourier transform algorithm is a major advancement in the field of Fourier analysis. It is a versatile method for evaluating Fourier components and is particularly adaptable to the digital computer. This report presents a discussion of the fast Fourier transform and its application in the direct method of power spectrum analysis. A routine is introduced which estimates the first-order linear system through which white noise is introduced to create colored noise. A comparison between the analytical and experimental results is presented. Author
