Frf frequency response function

WebA Frequency Response Function (FRF) gives insight into a structure’s natural frequencies, damping, and mode shapes. Often, the FRF is displayed with units of acceleration (g) over units of force (N) resulting in an accelerance unit of g/N. However, there are alternative formats with which the FRF can be displayed ( Figure 1 ).
