Claim Text:
1. A method comprising: determining at a computational device a measure of uncertainty for an estimate of a power spectral density of a noise signal, wherein the estimate is determined by computing an average of n power spectral densities derived from n respective sets of samples of the noise signal, wherein each of the n power spectral densities is computed based on a corresponding one of the sample sets, wherein said determining the uncertainty measure includes computing the uncertainty measure based on the number n, wherein said determining the uncertainty measure includes computing an effective number of independent averages corresponding to said power spectral density estimate based on data including the number n and a relative amount of overlap between successive ones of the n sample sets, wherein the uncertainty measure is computed based on the effective number of independent averages; and storing the uncertainty measure in a memory.
