1st guess: -0.25 V
(too high)
X=11??
2nd guess: -2.25 V
(too low)
3rd guess: -1.25 V
(too low)
X=1110
X=111?
4th guess: -0.75 V
(too high)
Make successive guesses and
use a comparator to tell
whether your guess is too high
or too low.
Each guess determines one bit
of the answer and cuts the
number of remaining
possibilities in half.
