Name: (4) (10 pts) Design a Moore FSM that has one input A and one output Y, and the output Y should be 1 if A has been 101 during the most recent three consecutive clock cycles or A has been 1 during the two most recent consecutive clock cycles. You only need to write down your state transition diagram. (5) (6 pts) Consider the following sequential circuit. Each two-input OR gate has a propagation delay of 130ps and a...

3) Recall that a flip-flop is built from 2 latches cascaded in the master-slave configuration as shown in Figure S. Assume that each latch has a D-to-Q propagation delay of 5ns and a D to-Q contamination delay of 2ns. The inverter has a propagation delay of 5ns and a contamination delay of ens. If you were the designer of this flip-flop, what would you report as the setup time and hold time of the flip-flop? D latch (master) D latch...

2. A four-bit addition machine is built with four full adders
such that the carry out of the first adder is the carry in to the
second adder, and the carry out of the second is the carry in to
the third, and so on as shown in Figure 2.
The machine has input and output registers and must complete the
addition in one clock cycle.
Each full adder has the following propagation delays: 20 ps from
Cin to Cout...

used 2. (10 points) Design a sequential circuit, which has the potential of being combinational lock" if the number of inputs is expanded. The circuit has four inputs, labelet as reset, codeo, codel, and code2, and one output, labeled as match. Binary bits are coming to the four inputs sequentially, one bit at a time for each clock cycle. After reset - 1 for one clock cycle, the circuit searches for the first occurrence of the...
