Model-Based Engineering for Complex Electronic Systems

Chapter 11

Statistical and Stochastic Modeling

11.1 Introduction

If we consider a typical design process, as we have described so far in this book, there is a development of the design from an initial specification, through conceptual design, to detailed design and finally optimization. This is worthy and necessary; however, in the “real world” we do not usually have quite such a deterministic situation. In practice, there is an inherent variability in both the parameters and intrinsic behavior of components that must be considered. For example, we have already used the simple example of a resistor that obeys Ohm’s law (V=I·R) that in practice may not be an entirely realistic model. We have already discussed in Chapter 7 how the thermal interaction ...
