thnku sir

Dear Students Don’t wait for solution post your problems here and discuss ... after discussion a perfect solution will come in a result. So, Start it now, replies here give your comments according to your knowledge and understandings....

Aoa any one have past final pprs???

Question No.1                                                                                                                   (5 Marks)

 

a)      Calculate the bandwidth required of the given AM Station with proper unit.

  • Modulating signal with bandwidth of 7 KHz.

 

Bandwidth of AM signal (modulated signal) = 2 * bandwidth of modulating signal

2 * 7 = 14 KHz

 

b)     Calculate the bandwidth required of the given FM Station with proper unit.

  • Modulating signal with frequencies of 10000 to 19000 Hz.       

 

Bandwidth of FM signal (modulated signal) = 10 * bandwidth of modulating signal

                            BW = 10 * 9000 Hz = 90000 Hz

 

 

 

Question No. 2                                                                                                                       (5 Marks)

 

Suppose, if the bandwidth of the medium is 16,000Hz and the difference between the two carrier frequencies (fc1 and fc0) is 2000Hz, and the transmission is in full duplex mode. Find the maximum baud rate for FSK signal in each direction with all necessary calculation and proper unit.

 

BW required for FSK is equal to the Baud rate of the signal plus the frequency shift

o Frequency Shift=Difference b/w two carrier frequencies

o BW= (fc1 – fc0) +Nbaud

 

Solution:

For FSK, if fc1 and fc2 are the carrier frequencies, then:

BW=Baud Rate + (fc1 – fc0)

Baud rate is the same as bit rate

BW=16000 + (fc1 – fc0) = 16000 + 2000 = 18000 Hz

 

 

 

Question No. 3    

                                                                                                                                                (5 Marks)

a)      What is the functionality of  splitter in cable modem?

 

The splitter directs the TV bands to the TV set and the Internet access bands to the PC

 

b)      Calculate the Effect of noise on Parallel Flat Wire by using following diagram?

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The total effect is 20 – 16 = 4
