I need to design a counter diagram that follows a count sequence 0-2-4-1-0 using DFFs.
The characteristic equation for the DFF is Q+ = D. I have the sequence in the present state and next state table but don't know where to go from there.
I appreciate any help. I have been trying to find a similar example for hours with no luck.
I think what the main thing I need help with is how to go from the state table to the k-map. If what I have done in the state table is correct. So I guess the first question is, is my state table correct?
Thanks for your help

Present State | Next State|Da |Db |Dc |
000 | 010 | 0 | 1 | 0
010 | 100 | 1 | 1 | 0
100 | 001 | 1 | 0 | 1
001 | 011 | 0 | 1 | 0
011 | 000 | 0 | 1 | 1
