1.69 For the circuit shown in Fig. P1.69, 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 R 1 = 10 k, R2 = 40 k, and C = 1 μF, find f0. What is the value of |T(jωo)|?
