CS601 Data Communication Assignment No 3 Solution & Discussion Due Date:04-06-2012

Q. 1. Suppose you have been asked to give a proposal of a Local Area Network for a company which requires easy reconfiguring, efficient in speed and economical in cost network. Considering these three factors, which guided media you will prefer for this type of network? Give three good reasons to support your answer.

(2 Marks for suggestion/name of media and 3 marks for three reasons) [2+3 = 5]

 

 

Q. 2. Analog signals are considered more prone to Noise as compared to digital signals. Suggest a proper method or technique with its complete steps for a telecommunication company which wants to convert its analog signals in digital signal to avoid from noise.

Note: just name the technique and its steps, detail is not required.  [5 Marks]

 

 

Q. 3. In Data Communication, situations exist where we need to change the Digital Signals into Analog Signals.  Select the technique(s) which is/are used by modems for this purpose. Choose all that apply. [10 Marks]

 

  1. B8ZS
  2. Quantization Amplitude Modulation
  3. Amplitude Shift Keying
  4. Frequency Shift Keying
  5. Frequency Modulation
  6. Frequency Reducing Key
  7. Frequency Division Multiplexing
  8. Phase Shift Keying
  9. Phase Modulation
  10. Quadrature Amplitude Modulation
  11. Manchester Encoding Scheme
  12. 4 PSK

 

 

Note:

 

  • Assignment should be in your own wordings not copied from Internet, handouts or books.

 

  • Your answer should be “to the point”.

kia ye correct soultion h?

Anyone Agree with this Solution

According to me this is Correct...

tehreem thanks ke ap ko sol mil gaya :)

plz dont copy paste

BOL :)

The complete solution is attached . Its my own solution please confirm it before uploading

Thanks

Asif Mahmood

 Asif Mahmood gud keep it up  one more thing always try to don't share your original solution which you also send your teacher. Otherwise it will be chance to get zero marks due same copy. Always try to share idea. thanks for understanding
