What is the advantage of spectrum widening in RZ encodings?
. Majority of signal energy lies in frequencies less than 0.5 of
the symbol rate
R = 1/Tb.
2. Small spectrum at dc facilitates carrier tracking, and important
in tape
recording with poor dc response.
3. Small spectrum at dc, lower magnetic-tape recording speed can be
used
(higher packing density is possible).
4. Insensitive to 180o phase ambiguity common to NRZ-L and
Manchester
coding.
5. Bandwidth requirements are approximately half those needed by
Manchester
coding.
Describe in a short sentence what the state machine below does. Using binary state encodings, complete a state transition table, output table, write Boolean equations for the next state and outputs, and sketch the FSM schematic. Inputs: A, B. Output: Q. (38 pt) 4. Reset S2 S0 Q: 0 S1 Q: 0
Why do we use binary encodings to represent information in the computer? What would be the pros and cons of using base-10 instead of base-2? Think about examples of abstractions we use with the computer on a regular basis. What are some metaphors provided by applications or your operating system? Compare RAM with nonvolatile memory like the computer’s hard drive. List the features of each, and compare them with each other? Where they differ in design, why would the designers...

Please Calculate the expected PW value for building and widening a two-lane bridge. Will rate highly. A bridge is to be constructed now as part of a new road. An analysis has shown that traffic density on the new road will justify a two-lane bridge at the present time. Because of uncertainty regarding future use of the road, the time at which an extra two lanes will be required is currently being studied. The estimated probabilities of having to widen...

Briefly define what is meant by competitive advantage. Are competitive advantage and sustained competitive advantage identical concepts? Compare and contrast the two concepts.
A survey of property owners' opinions about a street-widening project was taken to determine if owners' opinions were related to the distance between their home and the street. A randomly selected sample of 100 property owners was contacted and the results are shown next.

What is an advantage and a disadvantage of breastfeeding for both the child and the mother? What is an advantage and a disadvantage of formula bottle feeding for both the child and the mother? What may influence the choice to either breastfeed or formula bottle feed?
What does the term "absolute advantage" mean? What is the “principle of comparative advantage”? Explain why the principle of comparative advantage is relevant to international trade policy. Is everyone better off when trading is allowed?
What are comparative and absolute advantage? Why is comparative advantage, in your opinion, relevant for international trade?
