PS Sign

Output sign of input physical signal


Physical Signals/Nonlinear Operators


The PS Sign block returns the sign of the input physical signal:

  • The output is 1 when the input is greater than zero.

  • The output is 0 when the input is equal to zero.

  • The output is –1 when the input is less than zero.

Both the input and the output are physical signals.


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