Abstract
This contribution addresses the problem of finding a simplified but effective high-level representation of non-linear high-frequency systems, specifically amplifiers, which may exhibit considerable underlying complexity at the detailed circuit/device level of implementation. Two approaches are pursued, one being based on conventional narrow¿band representations, but exploring the fact that different such realisations are possible from the same set of measured (or simulated) terminal data, not all of which exhibit comparable accuracy of representation. The second approach is based on a discrete-time Volterra formulation offering considerable generality and improved computational properties.
