After years of dealing with the extremely slow elevator in the ist building, a new and improved one was finally installed. as a recent grad of cmpen 270, you are called upon to design the controller for the new elevator. the inputs (x, y) for this controller are designated as follows:
col1 xy operation
col2 00 no request (stay on the same floor)
col3 01 move to first floor
col4 10 move to second floor
col5 11 move to third floor

because this new elevator is super-fast, it can travel to any floor in a single clock cycle. for example, the floor 1 state can go directly to floor 2 or floor 3. an indicator light (call this output ) is on (z - 1) to remind people to enjoy the view because they are presently on the top (third floor) and off (z = 0) for all the other floors.

a. is this state machine best implemented as a mealy or moore machine? explain your reasoning.
b. assume that each state corresponds to a different floor. draw the state machine diagram that describes the operation of the elevator controller. provide the state transition table corresponding to this state machine diagram
c. design the sequential circuit using d-flip flops and draw the circuit
