Hello Everyone, Not been on here for a while, sorry!
my question is about masking...
I have an A level electronics exam in a couple of weeks, and one of the papers is on control systems.. one of the things that keeps coming up is masking. However, the teacher that teaches that side of the course is really, really, really bad (it's not just me.. as a class we saw the head of department to express our concern before christmas. and her lower 6th classes are the same). We haven't covered masking, and she doesn't know what to do..
thats why I am coming here!
as part of the course we learn Qbasic, and that what the question relate to..
here is a link to an example paper (with mark scheme):
Question Paper
Mark Scheme
if you look to page 19 you will see what I'm talking about.
what is the AND function, OR function (and any other that I might not realise!)
All I know is that the AND function and's them together and you can use it to seperate bits out, but thats all i know, and that is not a suitable answer.
Thank You,
Owen.
PS. can we have no comments about how hard/easy people think the paper is, it's not hepful this close to the exams......
