Two port network - part 3

This document discusses two-port networks and their hybrid and transmission parameters. Hybrid parameters describe a two-port network using its input and output relations when either port is open or short circuited. Transmission parameters describe a two-port network using ratios of output to input voltage and current. The document provides examples of calculating the hybrid and transmission parameters for simple circuits. Learning extensions ask the reader to determine input impedance and transmission parameters for additional examples.
