IN_f

Regular Input Port

Block Screenshot

Description

This block represent a regular input port. It must only be used inside a Xcos Super Block and be connected to a regular input in the subsystem.

This block is a signal link from outside of a system into a sub-system. In a Super Block, the regular's input ports must be numbered from 1 to the total number of regular's input ports. You can set it with the Port number parameter.

Data types

  • Output : same type that the input connected to it in the sub-system.

Dialog box

  • Port number

    An integer defining the port number.

    Properties : Type 'vec' of size 1.

Default properties

  • always active: no

  • direct-feedthrough: no

  • zero-crossing: no

  • mode: no

  • regular outputs:

    - port 1 : size [-1,-2] / type -1

  • number/sizes of activation inputs: 0

  • number/sizes of activation outputs: 0

  • continuous-time state: no

  • discrete-time state: no

  • object discrete-time state: no

  • name of computational function: input

Example

In the following example the Super block is an amplitude modulator. The IN_f block is used as a modulation signal input. Its data type is defined by the input type of the gain block that is a scalar double data type. Open this example in Xcos.
