How to design an impulse input in Matlab Simulink

Click For Summary
SUMMARY

To design an impulse input in a Matlab Simulink model, utilize two step input blocks to create the desired effect, as there is no dedicated impulse input block available. The solution involves configuring one step input with a delay and subtracting it from another step input to achieve the impulse response. Understanding the definition of an impulse is crucial, as it clarifies the relationship between the delay and the amplitudes of the step functions. This method effectively simulates an impulse input for various applications in control systems and signal processing.

PREREQUISITES
  • Familiarity with Matlab Simulink environment

Homework Statement


I would like to know a way to design an impulse input in a Matlab Simulink model. I know there are step input and ramp input blocks but there is no impulse input block.

an easy solution can be found using two step inputs. since this is in homework, I'll let you try to figure out the rest. if you still have trouble let us know.

Is this it? Or do I have to run one step input through a delay?

close but not quite... what you said about the delay is correct. there is also one more mistake as well

also to consider... how do you define an impulse? that will show you the relationship between the delay and the amplitude of the step functions.

hint. Maybe you need to subtract one step function from the other??
