This will help

http://www.antonine-education.co.uk/Electronics_AS/Electronics_Module_1/Topic_2/topic_2_logic_gates_and_boolean_.htm

Basically the Boolean expression for the And gate is

Q=A.B

And the Boolean expression for the OR gate is

Q=A+B

Thanks alot guys, repped u both

F=a . (b+c) + B.c + A.c

argh, cant do bars.

well is F= a(bar) . (B(bar).C(bar)) + B.C + A.C(bar)

if u get me lol

Are you trying to simplify it or does it have a circuit diagram?

Are you trying to simplify it or does it have a circuit diagram?

It just says "Using software package construct the following circuit and complete truth table"

then gives me the equation

Im a little rusty with this am afraid. havent done this in ages
But you need to do the circuit diagram before the truth table

But a bar menas you are using not gates

am not sure but i think this is the truth table
