library.e.abb.comresolution from a Fourier-analysis calculated from 200 ms time window of the measured signal are summed together around the harmonic frequencies. For example, in a 50 Hz grid the 5th harmonic is at 250 Hz frequency. Without grouping the value of the harmonic will be the RMS value of the spectral component at 250 Hz frequency only.

The z-transform and Analysis of LTI Systems
web.eecs.umich.eduThe z-transform and Analysis of LTI Systems ... The infamous harmonic series is an innite series that converges to innity: 1+1=2+1=3+1=4+ = 1: Some innite series simply do not converge, e.g., 1 1+1 1+ = ? The z-transform of a signal is an innite series for each possible value of z in the complex plane. Typically only some of those
Experiment 12: Simple Harmonic Motion
www.phy.olemiss.eduOne example of a harmonic oscillator is a spring that obeys Hooke’s Law (F = −kx). The period of an ideal, massless spring is related to the spring constant, k (or spring stiffness), and the mass of the object, m, that it moves: T = 2π m k The other harmonic oscillator modeled in this experi-ment is the ideal simple pendulum, whose period is

oak.ucc.nau.eduINTERPRETING THE ONE-WAY ANOVA PAGE 2 The third table from the ANOVA output, (ANOVA) is the key table because it shows whether the overall F ratio for the ANOVA is significant. Note that our F ratio (6.414) is significant (p = .001) at the .05 alpha level. When reporting this finding – we would write, for example, F(3, 36) = 6.41, p < .01. The F indicates that we are using an F test (i.e ...
