When designing a Mealy vs Moore machine, the Mealy will have more arrows coming from
each state than the Moore, which is why the Mealy can be done with fewer states. - CORRECT
ANSWER-False
Given a circuit with 3 inputs, when you draw the state transition diagram, how many arrows
will come out of each circle if it's a Moore Machine?
What if it's a Mealy Machine? - CORRECT ANSWER-Moore - 8
Mealy - 8
When assigning binary values to the states, it doesn't matter which values you pick - it always
works out to the same amount of logic. - CORRECT ANSWER-False
If the number of outputs exceeds the number of inputs by more than 2, extra states need to
be added to the design in order to account for the excess. - CORRECT ANSWER-False
Which of the following can be used to ensure flip-flops and latches start up in a known state?
- CORRECT ANSWER-Set and Reset
, For a positive edge-triggered memory element, the time the data input must be stable before
the positive clock edge is - CORRECT ANSWER-Flip Flop set up time
For a positive edge-triggered memory element, the time the data input must be stable after
the positive clock edge is - CORRECT ANSWER-Flip Flop Hold time
The time the data input must remain stable after the transition from transparent mode to
storage mode is - CORRECT ANSWER-Latch Hold time
The time the data input must remain stable before the transition from transparent mode to
storage mode is - CORRECT ANSWER-Latch Set Up time
A latch is constructed by using multiple flop-flops. - CORRECT ANSWER-False
The set and reset signals only affect the output of a flip-flop on the active edge of the clock.
For example, the reset on a positive edge triggered flip-flop only has an affect on the rising
edge of the clock. - CORRECT ANSWER-False
What is the minimum number of flip-flops needed to hold the state bits if there are 37 states?
- CORRECT ANSWER-6
What is the minimum number of flip-flops does needed to hold the state bits if there are 11
states? - CORRECT ANSWER-4
A single 2-to-4 decoder with an active low enable can be used to create the logic of a 3-input
NOR gate without requiring any additional logic. That is, one of the four outputs will provide
this function. - CORRECT ANSWER-True
