Question

How many known variables do we need to perform a linear analysis of a transistor circuit taking source resistance into account?

(a) 3

(b) 5

(c) 6

(d) 4

The question was asked in an international level competition.

My enquiry is from Transistor Amplifier Response, Taking Source Resistance into Account topic in division High Frequency Transistor of Electronic Devices & Circuits

Answer 1

Right choice is (d) 4

The best I can explain: There are a total of 6 variables in a transistor circuit taking source resistance into account. A transistor is a three-terminal device with each terminal having current and voltage measurements. We require any four variables to determine the other two variables of a transistor circuit taking source resistance into account.
