Chapter 3, Problem 3.67(choose chapter or problem)
a) The fixed-attenuator pad shown in Fig. P3.67 is called a bridged tee. Use a \(\text { Y-to- } \Delta\) transformation to show that \(R_{\mathrm{ab}}=R_{\mathrm{L}}\) if \(R=R_{\mathrm{L}}\).
b) Show that when \(R=R_{\mathrm{L}}\), the voltage ratio \(v_{o} / v_{i}\) equals 0.50
