Introduction.

Workshop PG5 Exercise Chapter 4
The function of the exclusive OR gate is that when one of the inputs are high,
then the output is high. If more than one of the inputs is high, then the output is
low. You can have 2 to 10 inputs, but only one can be high, to activate the output.
Erase the lines that are connected to the right column. Paste 2 exclusive OR
gates between the comparaters and the right column. Each gate should have 2
inputs. Delete Output1 and Output3 from the right column. Connect the outputs
from the 2 top comparaters to the inputs of the top exclusive OR gate. The outputs
from the bottom 2 comparaters should then be connected to the bottom exclusive
OR gate. The output of the top exclusive OR gate should be connected
to Output0 and the bottom one should be connected to Output2. Something
similar to the drawing below.
