Q. The equivalent noise temperature of a network given the noise figure of the network or system is:
✅ 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.
