10 Jul .The lower the Signal-to-Noise ratio the worst it is for telecomm, engineering homework help
Question Description
1.Your transmitter is capable of transmitting up to 8 Gigabits/second, your receiver can receive up to 10 Gigabits/second and the Capacity of the channel is 15 Gigabits/second. Which of the following statements are wrong IF any? (Assume there is no noise)
a.Changing the transmitter to a one capable of transmitting 15 Gigabits/second) will increase the capacity of the channel.
b.CHANGING the receiver to a one capable of receiving 15 Gigabits/second) will increase the capacity of the channel
c.If another media with capacity 25 Gigabit/second is used maintaining the transmission and reception rate of the original statement (transmitter:8 Gigabits/sec and Receiver 15 Gbits/sec) this will ensure to increment the transfer rate to 15 Gigabits/second.
d.Changing the transmitter to a one capable of transmitting 5 Gbits/second will make the receiver to operate at its proper receiver rate of 10 Gigabits/second
(4 points) Briefly explain your WRONG choices only (right choices with not sound or correct explanation à no credit)
2.Which of the following statements (or statement is) are TRUE about Signal to noise ratio (S/N) or Carrier to Noise (C/N) (2 points)
a.We have to decrease both, the signal and the noise power so there is no need for an equalizer.
b.The lower the Signal-to-Noise ratio the worst it is for telecomm.
c.When the signal has low power and the noise has high power, the C/N (S/N) ratio is pretty high.
d.C/N ratio is better when we diminish the noise power so the signal can be better differentiated
e.C/N ratio could not be calculated or controlled at all because noise can’t be measured.
f.C/N ratio is directly proportional to BW and then directly proportional to Capacity.
Briefly explain your choices (right choices with not sound or correct explanation à no credit)
3.Two telecomm engineers had trouble communicating equipment in one side Engineer “A” decided to assign a “1” = 100 Hertz and a “0” = 5 Hertz. In the other side engineer B, decide to assign a “1” = 5 hertz and a “0” = 100 hertz. The nature of the problem in this case is related to (2 points)
a.Distortion
b.Attenuation
c.Coding
d.Modulation
e.Noise
f.a) and b)
g.b) and c)
h.c) and d)
i.d) and e)
j.None of the above
Explain your answer and explain the nature of the problem (technical term), right choice and wrong explanation à Zero credit
4.If a cable (MEDIUM) has an fmin = 0.5 GHz and fmax= 3 GHZ, (G is for GIGA). Which of the following statements are true?
a.It is not possible to change the BW of the media even if we change the coding and modulation technique.
b.A signal of 1,000 GHZ will be severely attenuated when transmitted by this cable
c.With the above information, the BW of the media can’t be calculated however, the capacity and the speed are easily calculated.
d.The BW can be increased by improving equalization and by reducing the noise on the line.
e.A signal of 50,000,000 HZ will have no problem moving along this cable
Briefly explain the choices that you believe are TRUE and why. Right choice(s) with no right explanation à NO credit!(if more than one answer is true, you tell me which ones are true and why… PLEASE Only explain the one(s) that is (are) TRUE) (2 points)
5.Which of the following factors do(es) affect the “transfer rate” in a connection (2 points)
a.The receiver computer speed
b.The transmitter computer speed
c.The web server usage you are downloading from
d.The noise of the media involved
e.The size of the file transmitted
Briefly explain your choices (right choices with not sound or correct explanation à no credit)
