Question

A network either T or π, is said to be of the constant-k type if Z1 and Z2 of the network satisfies the relation? (a) Z1Z2 = k (b) Z1Z2 = k^2 (c) Z1Z2 = k^3 (d) Z1Z2 = k^4 This question was addressed to me in quiz.

Answer 1

Correct option is (b) Z1Z2 = k^2 To elaborate: Z1,Z2 are inverse if their product is a constant, independent of frequency, k is real constant, that is the resistance. k is often termed as design impedance or nominal impedance of the constant k-filter.
