electrical circuits

The well-known numerical-analytic method based on zeroes/poles matching (as z-transform realization) of equivalent transfer function or complex impedance (conductivity) in Laplace domain was proposed for high-speed computer analysis of electric circuits’ transients. The advantages of this method were illustrated on simple examples of the computer models of the first order electric circuit (RC-circuit that correspond to real pole) and second order electric circuit (RLC-circuit that correspond to complex pair of poles).
