It's a question in my assignment, which I don't really understand it. However, there is an example here.
e.g. A computer uses the following logical expression to control a finger print scanner.
F(A, B, C, D) = Σ (0, 1, 4, 5, 12, 14)
What will be the truth table of the function F?
The solution looks like this:

Can anyone explain how the truth table can be drawn from the function F? Thanks
What is under sigma notation is '1's and everything else is '0's
so take this table as the format and fill up it using '1's and '0's according to the sigma notation you got :) and simplifiy is using K-maps
