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.
