Specific mistakes that I saw in reports that were submitted this past week
Use size 11 font with a 1.5 line spacing. I was not this specific before and many of you
did fine. Some of you seemed to have size 14 font and double spaced.

Tracking ADC
This is one of the more interesting methods. Instead of just starting at a
midpoint and then guessing a solution, this ADC uses an up/down counter. The
counter is continuously clocked, and the up/down control line is driven by the
output of t

Number System
We know that the position of each digit in a decimal number is important and
has meaning depending on it location in the number. For example, lets look
at the number 435.2110. The 4 is the most significant digit and the 5 is the
