Trigger a pulse train based on control input in Simulink
显示 更早的评论
I am trying to trigger a pulse train or a packet of signal (amplitude modulated pulse) based on the control input. In other words, whenever the subsystem is enabled, a packet of data should be transmitted. I tried with enabled sub-system and repeating sequence stair blocks., but could not match the pattern.

could you post some screenshots of your output and what you done in simulink to have better understanding..

Have a look at the Stateflow documentation https://uk.mathworks.com/help/stateflow/gs/finite-state-machines.html. This is normally the best method for implementing this sort of behaviour.
If you attach your model then others can give more specific advice.

In this model, I tried to come up with a logic, that whenever the interogator sends a high signal, it triggers a countdown timer(6 time steps) and using that counter value, the custom signal is send across. But what I am intrested is, the rising edge of the interogator shall trigger a custom signal, which will be transmitted across. Here the custom signal is always running, and based on the counter value, it is send across.
I tried modifying the approximate edge function (State flow) based model, but it does not work on a continuous loop, rather only once per simulation., it triggered the state flow chart on the first rising edge but subsequent ones are not triggerred.

Hi Can you share how you are doing this with enabled sub system, that might help to resolve.
