1.71 For the circuit shown in Fig. P1.71, find the transfer function T(s) = Vo(s)/Vi(s), and arrange it in the appropriate standard form from Table 1.2. Is this a high-pass or a low-pass network? What is its transmission at very high frequencies? [Estimate this directly, as well as by letting s → ∞ in your expression for T(s).] What is the corner frequency ω0? For R1 = 20 kΩ, R2 = 100 kΩ, and C = 0.1 µF, find f0. What is the value of |T(jω0)|?
