Abstract

The biases and the variances are theoretically and experimentally investigated of fast Fourier transform (FFT) spectral estimates with different windows (data tapers) when used to analyze power-law noise types f 0 , f -2 , f -3 and f -4 . The experimental techniques introduced here permit one to analyze the performance of virtually any window for any power-law noise. This makes it possible to determine the level of a particular noise type to a specified statistical accuracy for a particular window Author(s) Walls, F.L. US Nat.
