When creating an average FRF, coherence functions can give indications of FRF quality, while estimation methods are used to account for noise on the measurements.

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 …

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.

Essentially, a Frequency Response Function (FRF) is the ratio between output (response of a structure/system) to input excitation. It is an inherent characteristic of systems and is unique to …

A common application of dynamic signal analyzers is the measurement of the Frequency Response Function (FRF) of mechanical systems. This is also known as Network Analysis, …

FRF is a frequency based measurement function. It is used to identify the resonant frequencies, damping and mode shapes of a physical structure. Learn more about FRF in this video.

This MATLAB function estimates a matrix of frequency response functions, frf, from the excitation signals, x, and the response signals, y, all sampled at a rate fs.

Unlike generating a FRF from a Finite Element Model, measuring a FRF may not return the same value every time a measurement is taken: structures are not completely linear and there can …
