For the network shown in Fig., evaluate the current I flowing through the 2Ω resistor using superposition theorem.

The value of R (in ohms) required for maximum power transfer in the network shown in Fig. is

The z-transform of a signal is given by c(z)=$${1 \over 4}{{{z^{ - 1}}(1 - {z^{ - 4}})} \over {{{(1 - {z^{ - 1}})}^2}}}$$. Its final value is
