Question 16

A K-F flip-flop works as follows. If KF=00, the next state is 1. If KF=01, the next state is the same as the present state. For KF=10, the next state is the complement of the present state. When KF=11, the next state is 0. (note: I have changed it slightly from the problem we did in class!)

Complete the table with KF inputs needed for the various state changes. Use don\'t cares whenever possible!!
