Question

What is the most efficient way to calculate voltage or current in a two – port network?

(a) Z parameters

(b) Y parameters

(c) H parameters

(d) G parameters

The question was posed to me during a job interview.

The question is from Two-Port Devices and Hybrid Model in chapter Small-Signal Low-Frequency AC models of Transistors of Electronic Devices & Circuits

Answer 1

The correct option is (c) H parameters

The explanation: We use H parameters or hybrid parameters to calculate the voltage or current of a two – port network. Z parameters stand for impedance parameters, Y parameters stand for admittance parameters and G parameters stand for inverse hybrid parameters.
