Description

This source block generates a piecewise constant signal the value of which can be set interactively using a TK widget in the course of the simulation. The output value is the value set by the slider (an integer between Min value and Max value) divided by the Normalization factor. Increasing proportionaly all three block parameters does not change the output range, but it does increase precision.

Dialog box

• Min value
  An integer specifying the min value in the range of the scale.
  Properties : Type 'vec' of size 1.

• Max value
  An integer specifying the max value in the range of the scale.
  Properties : Type 'vec' of size 1.

• Normalization
  The output of the block is the integer value specified by the slider (an integer between Min value and the Max value) divided by this Normalization factor.
  Properties : Type 'vec' of size 1.
