(A) Consider a sender wants to send a message “FRAME”, you are required to fill the empty column by using VRC even parity technique against given ASCII codes in following table.
(B) Calculate CRC,Quotient and No of Extra bits which will be added by using Module-2 Division Where Divisor=110011 , Message= 11100011 (5 Marks)
Question. 2 (5 Marks)
Four channels, each with a 50-kHz bandwidth, are to be multiplexed together. What is the
minimum bandwidth of the link if there is a need for a guard band of 20 kHz between the
channels to prevent interference?
Best of Luck

Qno1 B Answer
No. of extra bits=5
Total Channels=4 Total Frequency of one channel =50 KHz Total Guard Bands=3 Guard Band Frequecny =20 KHZ
Banwidth= Freq. of one channel *total channel + Guard band freq *Total guard bands Bandwith=50*4+20*3 Bandwidth=260KHZ
Question no 1(B)
check it out either it is OK or not..
u right dur e snawar
