Estimation Input Signals
Frequency response estimation requires an input signal to excite the model at
frequencies of interest. The software then measures the response at the specified output,
using the input signal and measured response to estimate the frequency response.When you perform frequency response estimation, you specify what type of input signal to
use and what its properties are.Offline Estimation
The following table summarizes the types of input signals you can use for offline
estimation in Linear Analysis Tool or at the MATLAB command line for use with
frestimate.Signal Description
Sinestream on page 5-37 A series of sinusoidal perturbations applied one after another.
Sinestream signals are recommended for most situations.
They are especially useful when your system contains strong
nonlinearities or you require highly accurate frequency
response models.Estimation Input Signals
