INTRODUCTION The voltage between the two terminals is the port voltage and the current into the system is known as the port current. With progressions in circuit structure, useful circuits in endless circumstances request a fixed hardware to be incorporated as part of larger network system. Two-port system study is useful frameworks fields of engineering, control frameworks, communications, and gadgets .The accompanying test experiment will endeavour to check the two-port hypothesis approach, so as to test its viability in simplifying circuit analysis. The two-port system is an electrical system circuit that has two sets (pair) of terminals which are connecting an electrical system to outer circuit .one sets (pair) of the two port is treated as input and another part as output. While each pair containing a solitary present and a solitary voltage.
