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

(D) none of the mentioned

Correct answer : Option (A) - gktb + gnadded

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.
