Q. The equivalent noise temperature of a network given the noise figure of the network or system is:
  • (A) t0(f-1)
  • (B) t0(f+1)
  • (C) t0(f)
  • (D) t0/f
💬 Discuss
✅ Correct Answer: (A) t0(f-1)

Explanation: the equivalent noise temperature of a network given the noise figure of the network or system is given by t0(f-1). in this expression, f is the noise figure of the system. t0 has the value 290 k. t0 is the standard temperature considered.
