Chapter 2, Problem 12E

Explanation of Solution

Explanation:

• The decimal value for each bit in the binary representation is equivalent to the corresponding powers of “2”.
• For example, consider the following bit configuration with “4” bits,
  • The “32” possible bit configurations using “4” bits is as follows,
