For the circuit given below, the value of input frequency which is required to cause a gain equal to 1.5 is _____________(a) 20 rad/s(b) 20 Hz(c) 10 rad/s(d) No such value existsThis question was addressed to me at a job interview.Question is taken from Advanced Problems on Magnetically Coupled Circuits topic in section Resonance & Magnetically Coupled Circuit of Network Theory
Answer» The CORRECT option is (d) No such value exists Easiest explanation: H (ω) = \(\frac{V_O}{V_i}\) = \(\frac{1}{1+jωRC}\) ∴ GAIN = \(\frac{1}{\sqrt{1 + ω^2 RC}}\) For any value of ω, R and C gain is ≤ 1.
