PS Dead Zone

Provide region of zero output for physical signals


Physical Signals/Nonlinear Operators


The PS Dead Zone block generates zero output when input signal falls within a specified region, called a dead zone. You can specify the lower and upper limits of the dead zone as block parameters. The block output depends on the input and dead zone:

  • If the input is within the dead zone (greater than the lower limit and less than the upper limit), the output is zero.

  • If the input is greater than or equal to the upper limit, the output is the input minus the upper limit.

  • If the input is less than or equal to the lower limit, the output is the input minus the lower limit.

Both the input and the output are physical signals.


Upper limit

The upper limit, or end, of the dead zone. The default value is 0.5.

Lower limit

The lower limit, or start, of the dead zone. The default value is -0.5.


The block has one physical signal input port and one physical signal output port.

Introduced in R2007a
