A M-F flip-flop behaves as follows: If MF = 01, the flip-flop changes state. If MF = 11, the flip-flop is set to Q = 0. If MF = 00, the flip-flop is set to Q = 1. The input combination MF = 10 is not allowed. (a) Give the characteristic (next-state) equation for this flip-flop. (b) Complete the table, using don’t-cares where possible. $$ \begin{array}{ll|ll} Q & Q^{+} & M & F \\ \hline 0 & 0 & & \\ 0 & 1 & & \\ 1 & 0 & & \\ 1 & 1 & & \end{array} $$ (c) Realize the following next-state equation for Q using a MF flip-flop: Q+ = CQ + DQ′. Find equations for M and F.
