Exercise 8.5 (Behavior of a Sequential Circuit Based on a System of Logic Equations). Calculate the behavior of the sequential circuit given in Fig. 8.2. Use the system of logic equations prepared in Exercise 8.3 as structural model. Practical tasks:

1 What type of finite-state machine is given by the sequential circuit in Fig. 8.2?

2 The sequential circuit depends on 2 inputs and includes 3 flip-flops, How many phases exist?

3 Solve the system of equations prepared in Exercise 8.3 and show the global list of phases.

4 Simplify the global list of phases that depends on all variables to a global list of phases that depends on the necessary variables to describe the behavior of the finite-state machine. Show the associated system function F(x, s, sf , y).

5 Store TVL system as e8201.sdt for later use.

6 Draw the graph of the analyzed finite-state machine and describe the visualized behavior.
