RESUMO

The influence of discretization methods to properties of digital models of a continuous system is studied. The object of the study consists in an oscillation system of the second order, which is discretizated by using formulas of numerical integration, the state space equation, and the method of invariance of the impulse characteristic. An equivalent proper frequency and equivalent damping coefficient are introduced in order to estimate characteristics of free oscillations of the discrete system of the second order.
