How to design an impulse input in Matlab Simulink

  1. Jan 28, 2016 #1
    1. The problem statement, all variables and given/known data
    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.

    2. Relevant equations

    3. The attempt at a solution
    If any working is needed please let me know

    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??
