                        Semester: Fall 2017

CS601: Data Communication

Total Marks: 10

 

Due Date: 14 July, 2017

 

Instructions:

Please read the following instructions carefully before submitting assignment:

You need to use MS Word document to prepare and submit the assignment on VU-LMS.

It should be clear that your assignment will not get any credit if:

 

  • The assignment is submitted after due date.
  • The assignment is not in the required format (doc or docx)
  • The submitted assignment does not open or file is corrupt.
  • Assignment is copied(partial or full) from any source (websites, forums, students, etc)

 

 

 

Objective:

 

The objective of this assignment is to learn about:

 

  • Transmission Impairments

 

 

 

 

Assignment 

 

 

 

Question  No. 1

Imagine a signal (P1) travels through an amplifier and its power is increased 20 times. This means that P2 (the amplified signal) =20P1.

You are required to calculate the amplification (gain of power) by writing all necessary calculations and formula.

 

Question No. 2

           

Suppose that S/N i.e. signal to noise ratio = 34dB and bandwidth of the channel is 2 kHz. You are required to calculate the theoretical channel capacity in bps by writing all necessary calculations and formula.

cs601 ki assignment chahiay

i need assigment 3 of cs601..if anyone have then send me 

Q#1: dB=10log10(P2/P1)
=10log10(20P1/P1)
=10log10(20)
=13

Rafia kia ap bta sakti hain k 13 kese aya hai

Take log of 20 which would be 13 and multiply with 10, the answer will be 13

main calculation kr rha hn pr ans 200 aa rha hai

Q#2:
C=Blog2(1+S/N)
put values in this formula and get answer

22580 bps is answer

CS601 assignment 3 solution

Question No. 1
Imagine a signal (P1) travels through an amplifier and its power is increased 20 times. This means that P2 (the amplified signal) =20P1.
You are required to calculate the amplification (gain of power) by writing all necessary calculations and formula.

Q#1: dB=10log10(P2/P1)
=10log10(20P1/P1)
=10log10(20)
=10 x1.3010
=13.010dB

Question No. 2

Suppose that S/N i.e. signal to noise ratio = 34dB and bandwidth of the channel is 2 kHz. You are required to calculate the theoretical channel capacity in bps by writing all necessary calculations and formula. 
Here, 
B = Bandwidth of the channel = 2 kHz = 2000 Hz
S/N = Signal to Noise ratio = 34 dB = 2511
Formula for Channel Capacity = B log base 2 (1 + S/N ) in bps
Putting the values in the formula: 
= 2000 log base 2 ( 1 + 2511)
= 2000 log base 2(2512)



2000 log base 2(2512)

Bro is formula ka mzeed koi solution hy ya bus yeah he answer hy.
