Question

The ratio of voltage transform at the first port to the current transform at the second port is called?

(a) Voltage transfer ratio

(b) Transfer admittance

(c) Current transfer ratio

(d) Transfer impedance

The question was asked in a job interview.

My enquiry is from Network Function for the One-Port and Two-Port topic in chapter S-Domain Analysis of Network Theory

Answer 1

The correct answer is (d) Transfer impedance

For explanation I would say: Transfer impedance is the ratio of voltage transform at first port to the current transform at the second port and is denoted by Z(s). Z21(s) = V2(s)/I1(s) Z12(s) = V1(s)/I2(s).
