Create a simulink model to plot the derivative of a step signal in a scope.

Create a simulink model to plot the derivative of a step signal in a scope.

[Paul]

The derivative of a step signal is a Dirac delta function, which can't be computed by Simulink, nor could it be plotted in a scope because scopes plot numerical data, not conceptual representations.

Hi @Abhaykumar,

To plot the derivative of a step signal in a scope, you can use derivative block and step function block and scope block of Simulink.

To read more about derivative block, you can refer here: https://www.mathworks.com/help/simulink/slref/derivative.html

To read more about step function block, you can refer here: https://www.mathworks.com/help/simulink/slref/step.html

To read more about scope block, you can refer here:

https://www.mathworks.com/help/simulink/slref/scope.html

I have attached a Simulink model with this answer for your reference.

Hope it helps!

Here's the documentation of Step, Derivative and Scope blocks in Simulink. Connect the blocks in the order of Step, Derivative and Scope to get the desired output:

• Derivative: https://www.mathworks.com/help/simulink/slref/derivative.html
• Scope: https://www.mathworks.com/help/simulink/slref/scope.html
