If you are having trouble with truth tables... then you my friend are in for a world of pain.

 

[Colt45]

F= ab' + b + a'c

F is 1 when:

ABC
10x
x1x
0x1

your dashes behind letters mean bar (the letter infront) right?

anyways then,

ABC - F
000 - 0
001 - 1
010 - 1
011 - 1
100 - 1
101 - 1
110 - 1
111 - 1

i think. /half asleep

what is this? a 3 input OR gate? A + B + C = F
unless im sleeping again

A B C
1 0 x
x 0 x
0 x 1

everything else F = 0. Easy enough?

Make three columns for a, b, and c, and a fourth column for your formula. In the first three columns place ones and zeroes so that every combination is covered. Then just write the result of each combination in the fourth column.
