I want to design 4 bit counter using D flip flop that will count 0 to 7 number
truth table
N A B C
--- -------------------
0 0 0 0
1 0 0 1
2 0 1 0
3 0 1 1
4 1 0 0
5 1 0 1
6 1 1 0
7 1 1 1
1)How many D flip flop are need to Implement 4 bit counter
2)how to know what is present state and next state
truth table
N A B C
--- -------------------
0 0 0 0
1 0 0 1
2 0 1 0
3 0 1 1
4 1 0 0
