Q. Expression for noise of a two port network considering the noise due to transmission line and other lossy components is:

(A) gktb + gnadded
(B) gktb
(C) gnadded
(D) none of the mentioned
Correct : Option (A)

Explanation: 
 expression for noise of a two port network considering the noise due to transmission line and other lossy components is gktb + gnadded. here, g is the gain of the system. nadded is the noise generated by the transmission line, as if it appeared at the input terminals of the line.
