Objective:

To analyze the operation of sequential circuits, deriving their timing and state diagrams

  1.  

    1. Analyze the following sequential circuit by deriving the state table and the state diagram.

      Sequential Network 1

    2. Determine the timing diagram for J1, J2, K2, Q1, Q2 and Z
      (Assuming initially that Q1 = Q2 = 0).

    3. From the state diagram, derive the minimum input sequence that will go through all the transitions, starting from the reset 00 state. Tabulate the output and next states.

    4. Implement the circuit. Obtain the timing diagram for the inputs in A 2. Compare results.

    5. Apply the input sequence derived in A 3. Read the output and next states and compare the results. Demonstrate your circuit to the instructor.

  2. Repeat all of A for the following circuit:
