I have an assessment at the moment and one of the questions is about the conversion of an Analogue wave to Digital one. I know how it is graphed and the basic concepts but I have no idea how to express it being forced into a grid. I was wondering if anyone knew any websites or books which has simply information that I am looking for. I have searched the web but must of the stuff I am finding is making no sense to me and continues to involve theories in electronics. Thank you for any help in advance!
