Hi

I am not used ot filters, but I know there is a how to here: 
http://help.scilab.org/docs/5.4.1/en_US/DesignEllipticFilter.html (this 
is available in french also)
from there, i suggest you navigate throught the "see also sections"

you can also have a look here: 
http://help.scilab.org/docs/5.4.1/en_US/section_dbbac6be408104de3049eddefaf6b9c9.html

the content of this webpage is also available in your computer, type 
"help" in the console and navigate.

I hope the "how to" (1st link) will help you
