ABSTRACT
The instantaneous transmission of information between two systems is physically impossible. The presence of delays poses a fundamental constraint on any theory describing physical interactions. If the time scale of the delays is comparable to the time scale of the processes under consideration, then it becomes essential to include the delay explicitly in the models. The investigators have to deal with delay differential equations (DDE's). The chapter is concern with here with one such equation of DDE. It arises in the context of biomathematical modeling, and was first used as a paradigm for mixed delayed feedback systems. The presence of chaotic orbits in the map would imply the existence of chaotic solutions of the continuous time system. The design of a task specific electronic analog computer allows us to study in real time a physical system built so that it will be described accurately by a DDE.
