The circuit of Figure P11-12 consists of two stages - a voltage divider stage and an OP AMP stage.

(a) Compute the transfer function \(T_{\mathrm{V}_{1}}(s)=V_{\mathrm{X}}(s) / V_{1}(\) \(s)\).

(b) Compute the transfer function \(T_{\mathrm{V} 2}(s)=V_{2}(s) / V_{\mathrm{X}}(\) \(s)\).

(c) Compute the transfer function \(T_{\mathrm{V}_{3}}(s)=V_{2}(s) / V_{1}(\) \(s)\). Is loading present? Explain.

(d) Swap the two stages and find \(T_{\mathrm{V}_{4}}(s)=V_{2}(s) / V_{1}(s\) ). Is loading present? Explain.
