Hi,

I can't figure out how to simply model on Simulink (without using m-function or s-function) the following operation:

s(k) = (1/N) * [e(k) + e(k-1) + e(k-2) + .... + e(k-N)] with N>=1 configurable.
with e for input, s for output

Thanks in advance

You can use any of the filter blocks in the Discrete library.

E.g. the Discrete FIR Filter block with coefficients set to ones(1,N)/N where N is something you specify.

Thank you Phil.

It's a good idea but I can't figure out how to initialize the states with the Discrete Filter block on matlab R2007a.
