how can I keep track of last n sec of data at each time step in Simulink model itself?

Hello, I am implimenting some strategy in simulink model and for this at each time step I need to look back last 3 sec data and compare it with the current time step data. I am not able to find any block which can store the last n sec data in simulink model. I have tried memory block but it only stores one time step value. The data store block stores all the time steps data. is there a way i can access only some simulation time data at each time step?

Hi @Sowmya Payyavula

You can test out this Tapped Delay block. It can store data for the specified number of delay steps.

Thank you for the reply. It helped me. I used tapped delay with bit change detection and nor gate to get the output I wanted.
