In MATLAB, there are several functions and techniques available to perform frequency domain analysis. The most commonly used function is the Fourier Transform, which converts asignal from the time domain to the frequency domain. The MATLAB function fft() can be used to compute the discrete Fourie...

The Frequency Domain System Identification Toolbox has been extended with analysis tools of nonlinear system behaviour. Specially designed excitation signals allow the description of nonlinearity levels. By this, model verification becomes possible even if nonlinear error terms excess linear additive noise....
