Analog Modelling and Signal Processing

Many of the circuits considered in the second chapter contain nonlinear converters and amplifiers mentioned as ’black boxes’ with certain characteristics and output functions. It is explained in this chapter how to implement these boxes by means of analog circuits. After that the second approach of electronic modelling of dynamical systems, analog modelling, is described. Finally, methods of the implementation of two-terminal circuits with specified characteristics are presented. Before the study of analog circuits begins, used integrated circuits and their functioning aspects are discussed. The chapter is mostly focused on materials related to electronic modelling issues.
