Question

Barletts Bisection Theorem is applicable to ___________

(a) Unsymmetrical networks

(b) Symmetrical networks

(c) Both unsymmetrical and symmetrical networks

(d) Neither to unsymmetrical nor to symmetrical networks

The question was posed to me during an interview.

My enquiry is from Series-Parallel Interconnection of Two Port Network topic in section Two-Port Networks of Network Theory

Answer 1

The correct choice is (b) Symmetrical networks

Best explanation: A symmetrical network can be split into two halves. So the z parameters of the network are symmetrical as well as reciprocal of each other. Hence Barletts Bisection Theorem is applicable to Symmetrical networks.
