WebThe fatigue damage increases by a factor of 100 across the entire frequency spectrum. Figure 6: The FDS for a simulated NAVMAT test of K=7 with varied Transition Frequencies. Note how the higher Transition Frequency tests were only effective at the higher frequencies, but not across the entire frequency spectrum. WebA spectrum analyzer is a tool commonly used to visualize electronic signals in the frequency domain. Some specialized signal processing techniques use transforms that result in a joint time–frequency domain, with the …
