Question

What technique is used in Millers Theorem?

(a) Two – port network

(b) Hybrid parameters

(c) Grounding

(d) Short circuiting

This question was addressed to me in an international level competition.

The question is from Frequency Response topic in section Frequency Response of Electronic Devices & Circuits

Answer 1

Right option is (a) Two – port network

To explain I would say: In Millers Theorem, we use the equivalent two – port network of the given electrical circuit. We divide the circuit into two parts, each part representing a different port for easier analysis of the circuit.
