Note:
For the first two port network based on given Z parameters
From second equation
Substitute in first equation
Corresponding transmission parameters for first network are,
For the second network, as per given Y parameters
From second equation
Substitute in first equation
Corresponding transmission parameters for second network are,
For cascading transmission parameter matrices get multiplied
