Detailed Function Description
The block is used to create insensitivity to changes in value around the zero input value, with the size of the insensitivity determined by the DeadZone parameter. The transfer characteristic of the block is described by the following diagram
- In the input value range
< -DeadZone, DeadZone >, the block's output is zero - In the range
(-infinity, -DeadZone), the output is defined by a line with points[-DeadZone, 0] → [-FinalX, -FinalY] - In the range
(DeadZone, infinity), the output is defined by a line with points[DeadZone, 0] → [FinalX, FinalY]
