Homework Statement
Realization of given three functions
$$
\begin{array}{c} f_{1}=x_{1}\bar{x}_{2}\bar{x}_{3}+x_{2}x_{3}\bar{x}_{4}\\ f_{2}=\bar{x}_{3}x_{4}+x_{1}\bar{x}_{2}\bar{x}_{3}\\ f_{3}=x_{2}x_{3}\bar{x}_{4}+\bar{x}_{3}x_{4} \end{array}
$$
using the PLA.
Homework Equations
I don't know what to write here. Probably that according to Wikipedia, PLA should have ##2^n## AND Gates for ##n## input variables and for ##m## outputs from PLA, there should be ## OR Gates
The Attempt at a Solution
The thing is that I'm completely stuck on this problem and I don't even know how to begin. I do have a decent background in combinational logic circuits, but not in the PLA as I don't understand it at all. The solution, however, is known to be 3 AND and 3 OR gates.
Can someone please give me some information on how to begin solving this task? I don't think I need the full procedure, only some advice on where to begin or where to look.
Any sort of helpful information is welcomed.
