On the power spectrum of red noise
Webgeneral case that the spectrum of the stochastic process is not flat. In a previous paper, Vaughan (2005) (henceforth V05), we proposed what is essentially a generalisation of Fisher’s method to the case where the noise spectrum is a power law: SR(f) = βf−α (where α and β are the power law index and normalisation param-eters).

Web1 de abr. de 2002 · Paleoclimatic time series are often unevenly spaced in time, making it difficult to obtain an accurate estimate of their red-noise spectrum. A Fortran 90 … WebAbstract. We demonstrate a simple method for testing the significance of peaks in the periodogram of red noise data. The procedure was designed to test for spurious periodicities in X-ray light curves of active galaxies, but can be used quite generally to test for periodic components against a background noise spectrum assumed to have a …

Figure 1 also shows the temperature anomaly spectrum. The spectrum plot is characterized by increasing power at lower frequencies. This is the fundumental characteristic of red noise processes.
