Abstract-The use of the fast Fourier transform in power spectrum
analysis is described. Principal advantages of this method area
reduction in the number of computations and in required core
storage, and convenient application in nonstationarity tests. The
method involves sectioning the record and averaging modified
periodograms of the sections.
