with a₀ = 2 × 105 and ω₀ = 10π. Find the frequency response H(ω) =V₂/V₁ and compare it with the frequency response of the circuit under an ideal op amp assumption (item a) as given in Problem 12-43.

Data from Problem 12-43

In the circuit of Fig. 12-72, assume R = 1 kΩ, C = 100 nF, and A = ∞. For each entry given in the following table, derive and verify the listed H( jω) and the magnitude Bode plot. Show that in all cases the filter is of first-order with ω₀ = 1/(RC) = 10000 rad/s.
