7. Comperator

THAT comperatorunit)	Comperator symbol

The comparator is a logic element which compares the signals a and b, at the THAT-comperator this panels are found on the left side, and gives a corresponding output, dependent on a and b.

The middle column (panel >0 and <0) holds the inputs given to the OUT panels.

If a + b is smaller than zero, the input at <0 is given to the output.

If a + b is greater than zero, the input at >0 is given to the output.

Comperators are very usefull or even necessary for many applications, for example when simulating a jumping ball, the prompt sign change in the movement direction can easily be modeled with a comperator.
