A FRF is a complex function which contains both an amplitude (the ratio of the input force to the response, for example: g/N) and phase (expressed in degrees, which indicates whether the response moves in and out of phase with the input).
Section Learning Objectives. By the end of this section, you will be able to do the following: Define amplitude, frequency, period, wavelength, and velocity of a wave. Relate wave frequency, period, wavelength, and velocity. Solve problems involving wave properties.
5.1.1 Examples of practical vibration problems. Vibration is a continuous cyclic motion of a structure or a component. Generally, engineers try to avoid vibrations, because vibrations have a number of unpleasant effects: Cyclic motion implies cyclic forces. Cyclic forces are very damaging to materials.

Amplitude is the maximum displacement of the particle from its rest point. In a longitudinal wave, the distance from the equilibrium position in the medium to compression or rarefaction is the amplitude.

We saw in Lecture 13, that the free vibration of a mass-spring system could be described as an oscillatory interchange between the kinetic and potential energy, and that we could determine the natural frequency of oscillation by equating the maximum value of these two quantities.

To construct something narrower than a constant, one needs more and more wavenumbers. To construct a very sharp Gaussian in x (σx→ 0) the Fourier transform flattens out: one needs an infinite number of wavenumbers to get infinitely sharp features. As you know, if we shift the Gaussian g(x + x0), then the Fourier transform rotates by a phase.
