The estimation of the response statistics of nonlinear systems subjected to Poisson-distributed pulse processes is addressed. The procedure to be followed is based on an extension of the traditional method of Ito stochastic differential equations where the increment of the Wiener process is substituted by the increment of a compound Poisson process. A general moment equation is derived which can be used for the calculation of the response statistics.
