1.Find the y-parameters of the network in Fig. 16.19-1 by
considering it as a parallel connection of a T-network and a
Π-network.
2.The [y] matrix of a resistive network is S.
Find the new [y] matrix if a 2 Ωresistor is connected (i) across
the input port (ii) across the output port and (iii) between the
upper input terminal and the upper output terminal.
3.Find [y(s)] matrix for the network shown in Fig. 16.19-2 by
considering it as a parallel connection of two two-port networks.
4.(i) Consider the circuit in Fig. 16.19-3 as a series connection
of two two-port networks, and thereby, determine its [z] matrix.
(ii) If the input ...
