20.6.6.3. Dead Zone
The Dead Zone block outputs zero output signal, if the input signal is less than the Upper parameter and greater than the Lower parameter. If the input signal is greater than the Upper parameter, the output signal is the input signal minus the Upper parameter. If the input signal is less than the Upper parameter, the output signal is the input signal minus the Lower parameter.

20.6.6.3.1. Example
We can test the Dead Zone block with the CoLink model shown in the below figure The Sine block is configured to a frequency of 1rad/sec and an amplitude of 1. The Dead Zone block Lower is set to -0.5 and Upper is set to 0.5. Set solver type to Fixed-Step, discrete (no continuous states), and let End time be 1.
