ND VARIATION in the signal (magnetic susceptibility) and x represents the expected level of the signal, then s/x can be thought of as a measure of the variability per unit of expected signal. Remember, a considerable variability in the signal (above or below average) might indicate bur- ied artifacts. Why, in this case, would a large CV be better or at least more exciting? Explain.
