Moving window in simulink during simulation

I want to calculate the maximum value of a signal within a fixed window size of previous values. How can I do this in simulink? I need to use this calculation during the simulation, so post-processing the final data is not an option. Here is a screenshot to illustrate my question.

Thanks, John

Try DSP System Toolbox - Statistics - Moving Maximum. You may want to put a Abs block in front of it as well.

I used this block, however, before this I need to add a rate transition block to digitise the signal. but it still gives an error, asking me to add a signal specification block before it. do you know what should I put in signal spec block? Thanks, Wasi
