14. One of the applications of Boolean algebra is the simplification
of switching networks. For example, the switching network
shown below can be simplified to a circuit consisting of only one
switch which performs the same function.
The switching network shown above is simplified as follows:
Step 1. Write the Boolean expression for the network.
A + AB
Step 2. Simplify the expression, using the basic laws of
A + AB = original expression
A = result of absorption (A + AB = A)
Step 3. Draw the switching network which represents the
