Information

This block transforms a Real input signal u into a Boolean output signal y:

• When the output was false and the input becomes greater than parameter uHigh, the output switches to true.
• When the output was true and the input becomes less than parameter uLow, the output switches to false.

The start value of the output is defined via parameter pre_y_start (= value of pre(y) at initial time). The default value of this parameter is false.
