The gray code is sometimes called a reflected code because the bit values are reflected on both sides of any

s of any 2" value. For example, as shown in Table 3-5, the values of the three low-order bits are reflected over a line drawn between 7 and 8. Using this property of the Gray code, obtain: a. The Gray code numbers for 16 through 31 as a continuation of Table 3-5. b. The excess-3 Gray code for decimals 10 to 19 as a continuation of the list in Table 3-6.
