Physicians use tissue electrodes to form the interface that conducts current to the target tissue of the human body. The electrode in tissue can be modeled by the RC circuit shown in Figure P 13.3-10. The value of each element depends on the electrode material and physical construction as well as the character of the tissue being probed. Find the Bode diagram for \(\mathbf{V}_{\mathrm{o}} / \mathbf{V}_{\mathrm{s}}=\mathbf{H}(j \omega)\) when \(R_1=1 \mathrm{k} \Omega, C=1 \mu \mathrm{F}\), and the tissue resistance is \(R_{\mathrm{L}}=5 \mathrm{k} \Omega\).
