Question

The expression of N in a full series equalizer considering Z1 as inductor and Z2 as capacitor is?

(a) Ro^2/(ωL1)^2

(b) 1+ Ro^2/(ωL1)^2

(c) (ω^2 L1^2)/Ro^2

(d) 1+ (ω^2 L1^2)/Ro^2

This question was addressed to me by my college director while I was bunking the class.

The question is from Series Equalizer in portion Filters and Attenuators of Network Theory

Answer 1

The correct answer is (d) 1+ (ω^2 L1^2)/Ro^2

Easiest explanation: The expression of N in a full series equalizer considering Z1 as inductor and Z2 as capacitor is N = 1 + X1^2/Ro^2 = 1+ (ω^2 L1^2)/Ro^2.
