This educational content explores circuit analysis, focusing on h-parameters in a network system. The diagram depicts a two-port network with specific h-parameters, interconnections, and questions for analysis. ### Diagram Description: The diagram displays a two-port network model with the following details: - **Voltage Source (Vg):** Represents the input voltage source. - **Zg (Source Impedance):** Given as 50 Ω. - **ZL (Load Impedance):** Given as 5000 Ω. - **Two-Port Network:** - h-parameters represented in a matrix form: - h11 = 100 Ω - h12 = 0 Ω - h21 = 100 Ω - h22 = 50 Ω - Arrows indicate the direction of currents I1 and I2 entering and exiting the network. ### Analysis Tasks: 1. **Find \( \frac{V_2}{V_g} \):** Calculate the voltage transfer ratio from the input to the output. 2. **Find \( Z_{in} = \frac{V_g}{I_1} \):** Determine the input impedance seen by the voltage source. 3. **Find \( \frac{I_2}{I_1} \):** Compute the current gain from input to output. This exercise involves understanding the relationship between input and output voltages and currents in a complex network, utilizing h-parameters. Calculations require substituting the given values into the h-parameter equations and solving for the required terms. ### Electrical Network Analysis This document provides a problem related to analyzing an electrical network.
