Analysis of a class of nonlinear discrete systems using multidimensional modified transforms

This paper presents an analysis procedure for determining the continuous output of a pulsed continuous-time system with small nonlinearities. The analysis technique uses Volterra series representation and higher-dimensional modified transforms. The method is compared and contrasted with the linear transform theory. Like the latter, it has certain advantages in treating cascaded and feedback systems, but the technique is more involved than in the linear method.
