Question (2): [25 marks] Part 1: [15 Marks] An incomplete register circuit is shown in the figure given below. a. Add the required connections to make the circuit work as a 3-bit universal parallel-in, parallel- out shift-right, shift-left register. b. Complete the register operation table shown below by adding the input values, the next state values and the actions (such as NC (No Change or Hold), Ld (Load), and ShR (Shift Right) and Shl (Shift Left)). c. Write the next state equations of the three flip-flops. Action Inputs Sh (shift) L(load) Next State Q2+ Qi Qo* 0 0 1 0 1 1 0 1 22 Q2H D2 21 D DO 10 10 11 Sh Ld CIK Part 2: (10 Marks] A U-N flip-flip works as follows: If UN=00 the next state of the flip-flop is 1. UN=01 the next state is the same as the present state. UN=10 the next state is the complement of the present state. UN=11 the next state is 0. a. Complete the following table (use don't cares when possible). UN Present state Q 0 0 1 1 Next state Q+ 0 1 0 1 b. Derive the next state equation of the U-N flip-flop
