11 Random Vibrations of Large Finite Element Systems,o‘eve vector of the loading the corresponding Karhunen-Loève vector of the response of the system is computed. This allows – applying the superposition principle – to calculate the covariance matrix of the output quantities (e.g. displacements, velocities etc.).

3 Spectral Analysis of Finite Dimensional Operators,A great number of engineering problems can be viewed as an input to output mapping, as shown in Fig. 3.1, where the system represents the law for the mapping between input and output. Mathematically speaking, the system represents an operator, which transforms input to output.
