Stochastic models of lumped elements

Abstract

Equations expressing the first and the second order moments for stochastic models of RLCM as well as R(t);L(t);C(t);M(t) elements have been derived in the paper. The analysis has been carried out for two cases. The first approach assumes that a stochastic current process describing a given excitation source and a random variable describing an element parameter are independent. The second one takes into account the relation between the current process and the random variable which are not independent in this case. The results have been illustrated by examples.
