1. The problem statement, all variables and given/known data
I need to obtain the minimum second order circuit of the function:

2. Relevant equations
3. The attempt at a solution
I know that in order to get the minimum second order circuit, I need to use K-Map using both miniterms and maxiterm and compare them. My problem is to put the expression in it's miniterms form.

Can you show us what your K-Maps look like?

but how can I show you my K-maps if I don't have my function in a miniterm or maxiterm form?

Just draw the 2x4 K-Map and map the 1's for the function you have listed. There is one simplification that comes out of doing this...

Ok, got it.

Its possible to draw the K-map because where is C.B for example, I can map 1's in the cells adjacents where only A changes.

thanks
