Question No. 1                                                                                                                                                                      

 

A below given diagram is representing the Differential Manchester encoding scheme. You are required to carefully analyze the diagram and then write the binary pattern represented by the diagram:

 

Hint: First bit is 0 and its voltage level is negative to positive.

 

Give your answer in the following table: (Solution )

 

0 1 0 0 0 1 1 1 0

 

 

Question No.2                                                                                                                                          

 

Determine the following from the diagram given below:

 

  • Period in Milliseconds
  • Frequency
  • Phase Shift

 

 

 

 

Give your answer in the following table:

 

Frequency Period Phase
0.001 milli seconds 0.001 mili seconds 180 degree

 

Question No. 3                                                                                                                                          

 

Suppose power P of a signal is increased 30 times after passing through an amplifier. By writing all necessary formulas and calculation steps, you are required to calculate amplification (power gain) in proper unit.

 

 

Solution:

Av=Input voltage/output voltage

AI=input current/out put current



 

Ap=av*ai

 

Amplifiers gain  given in decibels (dB)

 

Av=20logAv

Ai=20log Ai

Ap=10log Ap

 

 

Note calculate the values by your selfe

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Best of Luck!
