Q: MOD 6 Counter

Q- Can we design a MOD-6 counter using the above method?

Ans:  We firstly draw the state diagram

And now we draw the table to represent the desired output of the combinational circuit to reset FFs as:

Q2          Q1          Q0                          OUTPUT

0              0              0                              1

0              0              1                              1

0              1              0                              1

0              1              1                              1

1              0              0                              1

1              0              1                              1

1              1              0                              0

1              1              1                              0

And using K-map we get the combinational circuit as

And the complete circuit is as:
