EEE 120 Study Guide Questions with Correct Answers Latest Update 2025/2026
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. - Answers 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? - Answers 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. - Answers 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. - Answers False
Which of the following can be used to ensure flip-flops and latches start up in a known state? -
Answers Set and Reset
For a positive edge-triggered memory element, the time the data input must be stable before the
positive clock edge is - Answers 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 - Answers Flip Flop Hold time
The time the data input must remain stable after the transition from transparent mode to
storage mode is - Answers Latch Hold time
The time the data input must remain stable before the transition from transparent mode to
storage mode is - Answers Latch Set Up time
A latch is constructed by using multiple flop-flops. - Answers 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. - Answers False
What is the minimum number of flip-flops needed to hold the state bits if there are 37 states? -
Answers 6
What is the minimum number of flip-flops does needed to hold the state bits if there are 11
states? - Answers 4
