Question 16 of 20:

Convert the following value to base-2: 17.522. Take your answer to only 2 places to the right of the radix point (or binary point for base 2) and ignore any fractional part less than 0.25.

Question 17 of 20:

If a 2-bit Gray code starts with: 01 11

The next two values of the code would be:

Enter your answer as two, 2-bit binary values separated by a space.)

Question 18 of 20:

Which of the following is a valid 3 bit Gray code?

		110 -> 010 -> 001 -> 011 -> 010 -> 000 -> -> 101 -> 111
		000 -> 001 -> 011 -> 100 -> 101 -> 111 -> 110 -> 010
		000 -> 010 -> 100 -> 110 -> 111 -> 101
		110 -> 010 -> 011 -> 001 -> 000 -> 100 -> 101 -> 111
		100 -> 110 -> 010 -> 000 -> 011 -> 001

Question 19 of 20:

Get on the WWW and find an ASCII table. Write out the hex equivalent of the message: BYU-I

For this, assume that each character is represented by an 8-bit quantity (if the ASCII table you have found lists 7-bit codes, append a 0 to the left of the code to get an 8-bit code).

Also, remember that your answer is case sensitive (there are two different ASCII codes for each letter in the alphabet).

When writing your answer, put a space between each two hexadecimal digits that represent the ASCII values.

Example: Hi!

48 69 21

Question 20 of 20:

Write out the hex equivalent of the message: is hot!

where is interpreted as a LF (linefeed). A linefeed is "0A" on the ASCII table.

Represent each character by an 8-bit quantity. Show the code for the LF in the appropriate place in your solution. You will also need the ASCII codes for a space and exclamation point.

When writing your answer, put a space between each two hexadecimal digits that represent the 8-bit ASCII values.
