Hi guys, I have a question that i can't find the answer to: There's a given function: F=x+yz Then i have to show that F+F'=1 I found that F'=x'y'+x'z' therefore: F+F'=x+yz+x'y'+x'z' =yz+(xx')(xz')+x'y' =yz+x'y' i don't know how to go from here Have i done something wrong. Please Help....... thanks in advance cat
Hi, Oh Gee, aren't school teachers dull, dumb and delusional Whatever the (Boolean) function is, F + /F will allways yeild "1" as it's an OR of something and its opposite - That's basic Boolean !
thanks sooooo much oldbird hay soren, what you are saying is right but you know, poor students like us have to do the homeowrk that they give. otherwise we are screwed thanks for the comment anyways cat
LMAO Have the teacher refer to the "OR" gate truth table, because in an OR gate, an input, along with the same input inverted equals 1.
Except that you missed the point of the exercise. If you're too ignorant to figure it out, then I'm cetainly not going to enlighten you.
Two clowns in one day missed the point of the exercise. What's a poor student to do when faced with such boorishness.
