estimation of a power spectrum by averaging periodograms of overlapping windowed segments, trading resolution for lower variance.

In signal processing, Welch's method refers to estimation of a power spectrum by averaging periodograms of overlapping windowed segments, trading resolution for lower variance. This meaning comes from Welch (1967) in IEEE Transactions on Audio and Electroacoustics.[1]
