Finite system of relays II

This applet allows the user to verify that the three nonideal relays are switched on and off at the same time using either representation. Moving the scrollbar of the nonideal relays will move that of the `Discrete Preisach Plane' and vice versa.

The first tab has the relays randomly distributed within the range. If the refresh button on the browser toolbar is pressed the relays will be placed at other random positions. The second tab has the relays placed on a defined grid as explained in the text.

The input output diagrams of each appears on the right hand side of the applet. Notice that the red dot is always at the identical positions on the respective graphs. Pressing the clear button below either graph will delete all previous information on that graph
