Design a mod-12 Synchronous up counter.

Ans. Design of a mod 12 synchronous counter by using D-flipflops.

I state table
Present state Next state Required D Inputs

A	B	C	D	A	B	C	D	DA	DB	DC	DD
0	0	0	0	0	0	0	1	0	0	0	1
0	0	0	1	0	0	1	0	0	0	1	0
0	0	1	0	0	0	1	1	0	0	1	1
0	0	1	1	0	1	0	0	0	1	0	0
0	1	0	0	0	1	0	1	0	1	0	1
0	1	0	1	0	1	1	0	0	1	1	0
0	1	1	0	0	1	1	1	0	1	1	1
0	1	1	1	1	0	0	0	1	0	0	0
1	0	0	0	1	0	0	1	1	0	0	1
1	0	0	1	1	0	1	0	1	0	1	0
1	0	1	0	1	0	1	1	1	0	1	1
1	0	1	1	0	1	0	0	0	1	0	0

Firstly draw the state table containing present state, subsequent state and required flip-flop input to provide the transition. D flip flop offers the output similar as the next state itself. After that, solve through using K maps to determine DA DB DC DD for all states.
Unutilized states are 1100,1101,1110,1111 they can be function as don't care conditions from the table. Depict Karnaugh-maps for DA, DB, DC and DD as follows and acquire Boolean expressions for them.
