This course offers an introduction to the basic elements of analogue

computing and the use of such a coinputer in the solution of engineering

problems, by simulation.

The course covers the basic functional elements of an analogue con>-

puter, the basic computational functions, time and amplitude scaling

and the application of these features to the solution of a variety of

engineering problems.
