Linear Regression & ABCD Parameter(ABCD matrix) of 2 Port network- Eigen values Eigen Vector

Describe about the Equations for One Variable One Dependant Variable (One Input One output ), Multi Variable One Dependant Variable (Multi Input One output) , Multi Variable Multi Dependant Variable (Multi Input Multi output) and finding equations with available samples (Input Data & Output Data). Same method is used to find ABCD Parameters (ABCD matrix) of 2 port network . It is not explained about ABCD Parameters of 2 port network using the components used in the network. This is explained deeply in our earlier video. Small description of Eigen value , Eigen vector is explained in this video. Eigen value , Eigen vector application in ABCD matrix of 2 port network is explained with example. At one place , we mentioned as Note: No voltage/current dependent source in the T network. Generally we can connect network in cascade connection method. Final ABCD matrix is equal to multiplication of all matrix. If voltage dependent source or current dependent source is included in the network ,we do not do multiplication of all matrix.
