Output Director

Block-library: DUBSI

The Output Director block 'directs' an inputsignal to either the first, or the second output, depending on a threshold value. It is comparable to the Switch block in Simulink, except that this block switches between two output ports, rather than between two input ports.

If the input signals are called u₁ and u₂, and the output signals are called y₁ and y₂, then the following equations define the switching logic:

   if u₁ is greater than or equal to the threshold, then

        y₁ = u₂
        y₂ = 0

   else

        y₁ = 0
        y₂ = u₂

In other words: u₁ is the test signal that determines the output path for u₂. The threshold value must be entered by the user as block parameter for the block Output Director.

The block Circuit Selector from the same blocklibrary provides a similar solution for the selection and deselection of two mutually dependent circuits.
