===== Detailed Function Description =====

The block is used to eliminate the dead zone of actuators in response to a change in value. The size of the dead zone is determined by the //DeadZone// parameter. The transfer characteristic of the block is described by the following diagram\\
{{:cs:mervis-ide:35-help:inverteddeadzone_transfer.png}}\\

  * In the input value range ''< -Eps, Eps >'', the output of the block is zero
  * In the range ''(-infinity, -Eps)'', the output is defined by a line with points ''[-Eps, -DeadZone] -> [-FinalX, -FinalY]''
  * In the range ''(Eps, infinity)'', the output is defined by a line with points ''[Eps, DeadZone] -> [FinalX, FinalY]''

For eliminating common dead zones, the following settings are recommended:

  * Eps should be chosen from the range (0, 1), depending on how wide you need the zero output band to be
  * DeadZone should be chosen based on the actuator's dead zone, for example, for a 2-10 V output, select a value corresponding to 2 V
