**Problem 5: Thevenin Analysis for Input Resistance** For the small signal circuit provided, apply Thevenin analysis to derive an expression for the input resistance (\( R_{\text{in}} \)). **Note:** The variable "g" represents the gain of the current source. **Circuit Diagram Description:** - The circuit consists of an input resistance \( R_{\text{in}} \) connected in series with a resistor \( R_C \). - Parallel to \( R_C \), there is another resistor \( R_B \). - The circuit includes a dependent current source \( gV_B \), where "g" is the gain and \( V_B \) is the voltage across \( R_B \). - \( V_B \) is marked with a positive terminal on the top and a negative terminal on the bottom. **Objective:** Determine the expression for the input resistance \( R_{\text{in}} \) using Thevenin analysis of the given circuit configuration.
