1.A two-port network has [y] S. Find one network
that satisfies this specification and explain why that network
will have no [z] matrix.
2.A two-port network has [y] S. What is the nature
of the circuit – memoryless or dynamic? Is it a passive
network? If a 0.5 Ωresistor is connected directly across the
input port, find the new [y] matrix.
3.A resistor R is connected in series with the input port of a two-
port network. Derive expressions for y-parametersof the new
network in terms of y-parameters of the original network and R.
4.A two-port network has [z] Ω. Find one network
that satisfies this ...
