[PSD12] Exercise 3.10

[matypist]

Exercise 3.10 A JK flip-flop receives a clock and two inputs, $J$ and $K$. On the rising edge of the clock, it updates the output, $Q$. If $J$ and $K$ are both 0, $Q$ retains its old value. If only $J$ is 1, $Q$ becomes 1. If only $K$ is 1, $Q$ becomes 0. If both $J$ and $K$ are 1, $Q$ becomes the opposite of its present state.

(a) Construct a JK flip-flop using a D flip-flop and some combinational logic.
(b) Construct a D flip-flop using a JK flip-flop and some combinational logic.
(c) Construct a T flip-flop (see Exercise 3.9, #176 ) using a JK flip-flop.
