Design the clocked sequential circuit for below specifications, using D f/f.

1. the word description of the circuit is stated.

2. obtain the state diagram

3. number of states might be reduced /ot covered in this course

4. assign binary values to each state

5. determine number of f/f and assign letter symbol

6. choose type of f/f

7. implement the state table, derive circuit excitation and output table

8. using map-simplification derive the circuit output functions and the f/f input functions

9. draw the logic diagram.

D Flip-Flop \begin{tabular}{lll} \hline Q(t) & Q(t+1) & D \\ 0 & 0 & 0 \\ 0 & 1 & 1 \\ 1 & 0 & 0 \\ 1 & 1 & 1 \end{tabular} 1. the word description of the circuit is stated Four states: 01122330bya1bya0bya1bya1 Otherwise (for the other input bit) state remains unchanged
