Argument activity and norm of a function
Hi
How can we find the norm of the function, x1.x2 + x2.x3
Also, how to calculate the activity of the argument x2 in this ?

Thanks & Regards,
RT

Hello and welcome to the forum.

Could you provide more context? What is "."? What are the domain and the codomain of this function? What subject is this?

Thank you.

This is a boolean function.
y = x1.x2 + x2.x3
+ OR
. AND

(x1,x2,x3 ) = (0,0,0) ; y = 0
(x1,x2,x3 ) = (0,1,1) ; y = 1

Re: Argument activity and norm of a function
Sorry, I have not encountered the terms "norm" and "activity" in reference to Boolean functions. Do you have the definitions or references?
