3. The Network Input Port Output Port + _ _ + V 1 V 2 I 1 I 2 If a network is having two pairs of terminals or two ports then it is called as two port network. Two Port Network

4. N Port Network A network having N numbers of ports ; is called N port network.

5. Different Parameters Related To Two Port Network Impedance (z) Parameter Admittance (Y) Parameter Hybrid (h) Parameter Inverse Hybrid (g) Parameter ABCD Parameter Inverse ABCD Parameter

6. Z parameter The impedance or Z parameter of a two port network is defined by or in scalar form

7. Z parameter The Z parameters can be found from These parameters are call open circuit impedance parameters

8. Y parameter The admittance or Y parameter of a two port network is defined by or in scalar form

9. Y parameter The Y parameters can found from These parameters are call short-circuited admittance parameters

10. The defining equations are: I 2 = 0 V 2 = 0 I 2 = 0 V 2 = Transmission Parameter(ABCD)

11. Inverse Transmission Parameter

12. The h-parameter (Hybrid parameter) H-parameter is the combination of Z and Y parameter defined by or in scalar form H-parameter is commonly used in transistor modeling.

13. The h-parameter The h parameters can found from

14. g-parameter is defined by or in scalar form g-parameter is an alternative form of hybrid representation. Inverse Hybrid Parameter (G Parameter)

15. The g parameters can found from

16. Conversion of Two-port parameters Two port parameters can be converted to any form as follows From And and
