How to hold impulse signal in continuous time? (Simulink)

Question

I have a hard time getting an ideal step signal triggered by an impulse. I'm not able to hold the impulse at its peak.

In the pictures can be seen that I have some logic producing an ideal pulse with width = stepsize and amplitude = 1 (Scope 1) - but I need a step of the same amplitude. I tried a lot of stuff (memory elements, adding constants and so on) and came up with the idea above. I don't understand why it isn't working? Why don't I get amplitude = 1 for my step (Scope 2)?

Isn't there a better solution?

some facts:

• I just have the basic Simulink
• it's a time-continuous model
• convert is just inverting boolean to double to satisfy the switch conditions

Edit: It is very important that I only get a step for the first pulse, if it ever happens, that there is another pulse, the output should remain 1. (well that could be easily solved with a saturation block)

Answer 1

I had a little blackout, the solution for my case (impulse amplitude = 1) is pretty easy:

One could use a triggered subsystem with a constant.

Actually not even the constant is necessary:

Anyway, the question is not entirely answered, as it is just working for pulses of amplitude = 1. The trigger output is always 1!
