Frequency-domain modeling of continuous-time systems using the lattice algorithms

Two frequency-domain methods for modeling continuous-time system using the lattice algorithms are presented. In one of the methods, the frequency-domain data are sampled at a nonuniformly spaced frequency grid. This method is suitable for applications where the frequency response of the continuous-time systems can be measured explicitly. In the other method, the frequency-domain data are sampled at a uniformly spaced frequency grid. This method is suitable for applications where the frequency spectrum of the input and output signals are computed from the input and output time-domain data using the FFT (fast Fourier transform).<
