Chapter B, Problem 37E

Explanation of Solution

Graphical representation of finite-state machine:

The fake security device like electronic eye includes a row with three different lights with required specifications that are controlled by different outputs namely, left, middle and right.

Explanation:

• The above diagram describes about the graphical representation of electronic eye with finite-state-machine. The lights on the left side, middle and right side are denoted by L, M and R respectively.
• From the diagram, only one light can be switched on at a once and it follows the path from left to right and from right to left.
• If the next state signal is not received or any other disturbances occur in middle of the path then, the light will be switched on in the present state and paused till the signal is received or all the disturbance are cleared...
