If you take a look at the attachment that I have posted, you will see 4 wave diagrams labeled A, B, C, D, respectively. My objective to is to answer the questions after the A-D diagrams.

The first one is a AND logic gate with A and B. So how would I combine A and B. Do I draw only the highs of both and just copy the length of their intersection or what? Please be descriptive.

How would I draw the wave diagrams for OR? Is it when either of A or B has high point I draw it on my graph?
