2.30 The inverting circuit with the T network in the feedback is redrawn in Fig. P2.30 in a way that emphasizes the observation that R 2 and R3 in effect are in parallel (because the ideal op amp forces a virtual ground at the inverting input terminal). Use this observation to derive an expression for the gain (vO/vI) by first finding (vX/vI) and (vO/vX). For the latter use the voltage-divider rule applied to R4 and (R2 R3).
