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).
A frequency response function (FRF) is a transfer function, expressed in the frequency-domain. Frequency response functions are complex functions, with real and imaginary components. They may also be represented in terms of magnitude and phase. A frequency response function can be formed from either measured data or analytical functions.

The frequency response function (FRF) is defined as the ratio between response and excitation as function of excitation frequency. For unit excitation amplitude, FRF is given by Eq. (5.151). The response is a complex number, hence FRF will also be a complex number defined by magnitude |FRF| and phase θ.
Dec 10, 2023 · The Frequency Response Function (FRF) is a crucial concept in engineering and signal processing, particularly in the analysis of dynamic systems. It provides a quantitative measure of how a system responds to sinusoidal input signals across a range of frequencies.
May 22, 2022 · The term frequency-response function (FRF) is general, meaning physically the magnitude and phase in steady-state sinusoidal variation with time of some subject variable, relative to the magnitude and phase of some other reference variable.
The sweeping speed, in either octave/min if the sweep mode is logarithmic, or in Hz/Sec if the sweeping mode is linear. The amplitude of the sine signal, A (f, t), which can be a constant or a variable of time and frequency. ,Speed) represents the current frequency of the sweeping sine.
