What is the advantage of spectrum widening in RZ encodings?
What is the advantage of spectrum widening in RZ encodings?
Homework Answers
. 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.

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...
