In Moku:Lab's Phasemeter, Power Spectral Density (PSD) and the Amplitude Spectral Density (ASD) are calculated in the iPad App using Welch’s method of overlapping periodograms with a 50% overlap and a Hanning window. The number of points is either 512, 1024, or 2048 depending on the sampling rate chosen.
