The following equation defines the square function.

square(x) = 1, if 2n x < 2n + 1 and 0 elsewhere

Note  You can define more complex functions by varying and combining the Step Function, Spike Function, and Square Function VIs, respectively.

The following illustration shows the graph for square(x)*square(x – 0.8) in the interval (–4.0, 4.0).
