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.

Consider the combination of capacitors in Figure P16.38. (a) Find the equivalent single capacitance of the two capacitors in series and redraw the diagram (called diagram 1) with this equivalent capacitance. (b) In diagram 1 find the equivalent capacitance of the three capacitors in parallel and redraw the diagram as a single battery and single capacitor in a loop. (c) Compute the charge on the single equivalent capacitor. (d) Returning to diagram 1, compute the charge on each individual capacitor. Does the sum agree with the value found in part (c)? (e) What is the charge on the 24.0-mF capacitor and on the 8.00-mF capacitor? Compute the voltage drop across (f) the 24.0-mF capacitor and (g) the 8.00-mF capacitor.
