If cumulative is TRUE, NORMDIST returns the cumulative distribution function; if FALSE, it returns the probability mass function. The equation for the normal density function (cumulative = FALSE) is: When cumulative = TRUE, the formula is the integral from negative infinity to x of the given formula. Example.

2. The PSD is the Fourier transform of the auto-correlation function. ( The power can be calculated from a random signal over a given band of frequencies as follows: 1. Total Power in x(t): 2. Power in x(t) in range f1 - f2: 1The signal has to be stationary, which means that us statistics do not change as a function …
