FRF Estimation

Estimates the Frequency Response Function (FRF) for random excitation and response time domain data.

FRFESTIMATOR computes the Frequency Response Function (FRF) estimates for the random excitation and response data. The function is capable of calculating following FRF estimates;
(1) H1
(2) H2 and,
(3) Hv
The function returns the estimate value, coherence, frequency range and plots the amplitude and the phase plots of the FRF estimate with the frequency.
