Power Spectral Densfty (PSD) is the frequency response of a random or periodic signal. It tells us where the average power is distributed as a function of frequency. ( The PSD is deterministic, and for certain types of random signals is independent of time1. This is useful because the Fourier transform of a random time signal is itself random ...

The first cumulative frequency (2) is simply the frequency for the first class, so we enter the formula =D2 in cell E2. The second cumulative frequency (15) is equal to the frequency of the second class (13) plus the prior cumulative frequency (2), so we enter the formula =D3+E2 in cell E3.
