finding minimum.

Hi,

I know finding minimum in a normal way is easy. But i have a situation, If there is a input that gives out a sample every 1 second, and i need to find minimum for the first 30 samples. Is there a way to do it? I have used a buffer followed by a min block but this is delaying my whole model for some reason. I need a better way to do it. Could you please help me. Thank you so much,

Only for the first 30, do you need a "rolling minimum" of each window of 30?
