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
Correct : Option (A)

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.
