The quality of transmission depends upon

  • A.Nature of signal only
  • B.Nature of medium only
  • C.Both (a) and (b)
  • D.Neither a nor b

Answer: C

It depends on both the nature of the signal and the nature of the medium.

The signal's frequency and power determine how far it can carry and how much information it holds, while the medium fixes the attenuation, dispersion and noise it will meet. Neither alone decides the quality of transmission.
