Help with logic gates!!!! i am so confused!

[mat2317]

Hey does anyone here know anything about logic gates? I have this question and i just dont have a clue.... heres the question=

Three Logic Circuits are required for an Industrial Process:

Process A = (B.C)+ Not A

Process B = (A.B.Not C)+ (Not A.B.C)

Process C = (A . Not B)

Write the truth table for Process A
Draw the circuit for process B


LOL any ideas?

This brings back memories... its been a while but i dug out a textbook i have


Process A = (B.C)+ Not A

ABCF
0001
0011
0101
0111
1000
1010
1100
1111

I did the first one for you.... however, i suggest you get yourself a couple of textbooks... the ones i have are Advanced electrical and electronic engineering and Hughes electrical and electronic technology. these served me well.
considering you are struggling with these i would guess that you haven't done DeMorgen's theorem yet which is a real pain when compared to these.

also, wikipedia has some good information on what you are looking for http://en.wikipedia.org/wiki/Logic_gates
