For the [4:2] module of Figure 3.5, show that the value ofw < 4. Show the
input values for which w - 4.
Since the network for both columns is the same, why is it necessary to
consider two columns as the basic module when using the model of
Figure 3.4 ?
Show that the module is a [4:2] module.
Compare the implementations of Figures 3.5 and 2.41, in terms of delay
and number of equivalent gates.
Show a linear array of [5:2] modules, implemented as
