1. A process by which a system can be modeled on an analog computer by interconnecting analogous system components.

Such dynamic behavior can be simulated by altering circuit gains and reference voltages.

2. A procedure that is used for constructing a model of a system by using an analog computer, in which the model is devised at the console by interconnecting components on the basis of analogous configurations with real system elements.

By adjusting circuit gains and reference voltages, dynamic behavior can be generated which corresponds to the desired response, or is recognizable in the real system.
