Increment and Decrement Real-World Values

Open Model

This example shows how to increase and decrease the real-world value of a signal using the following blocks:

  • Increment Real World

  • Decrement Real World

  • Decrement Time To Zero

  • Decrement To Zero

The Scope block shows the output of a Sine Wave block with amplitude 5, as well as the real-world value of that signal incremented and decremented by one.

The Scope1 block shows the output of a Sine Wave block with amplitude 3, as well as the output of the Decrement To Zero and Decrement Time To Zero blocks:

  • The Decrement To Zero block decreases the input sine wave signal by one, and ensures the value never goes below zero.

  • The Decrement Time To Zero block decreases the input sine wave signal by the sample time, Ts, and ensures that the value never goes below zero.
