QUESTION 3 The following figure shows a sequential circuit with three D Flip Flops with a common input clock. Note that the inverted output of the first flip-flop ) is connected to the input of the second flip-flop (D input of the far right flip flop). Assume that the flip flops are initialized at '1'. That is, Q1 = Qo = 1 during Cycle 0. This means the output of this circuit is initially Q1Q0 = '11'. 1. Compute the value of each output signal (Q1, and Qo) for 10 cycles using the table below. 2.

A UV flip-flop behaves as follows: • If UV = 00, the next state of the flip-flop is the complement of the present state. • If UV = 01, the next state of the flip-flop is 1. • If UV = 10, the next state of the flip-flop is 0. • If UV = 11, the next state of the flip-flop is the same as the present state. A Moore sequential circuit has one input X and one output Z. The circuit outputs Z = 1 if and only if the number of 1's received as inputs is a multiple of 3. Derive a state table for this circuit and realize the state table with UV flip-flops. Label your states S, and make the encoding the binary representation of i. For example, S₂ should correspond to Q1Q2 = 10.

• Design a sequential circuit with two T Flip Flops, A and B, and two inputs, E and x. If E=0, the circuit remains in the same state regardless of the value of x. When E=1 and x=1, the circuit goes through the state transitions from 00 to 01 to 10 to 11 back to 00, and repeats. When E=1 and x=0, the circuit goes through the state transition from 00 to 11 to 10 to 01 back to 00, and repeats
