I have an input like this:

[2, 2, 2, 2, 3, 2, 2, 2, 3, 4, 4, 4, 4]

I want to suppress oscillation and only allow sequences that have had the same value for x seconds (e.g. 5). So that it outputs the above sequence like this:

[2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3]

Is there a way to do this using blocks in Simulink?

I still don't know why it would output [2, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3]. There has not been five consecutive '3' in the input data. If you want the data to only jump when the value is 5 times the same consecutively, the output will be:

Input: [2, 2, 2, 2, 3, 2, 2, 2, 3, 4, 4, 4, 4]
Output: [2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2]

Yeah, because you assume that the consecutive number is coming from the input, but it is about the output.

Using only blocks, I think this should do the trick:

Thank you very much. This is the solution that solved my problem:

However, this only helps me with the values that occurred in the last 5 seconds. Does anyone know how can I apply this to the last 50 seconds without adding 40 more delay blocks?
