Hello all, I had a lab pertaining to LOGIC gates, and the instructor drew something on the board (without elaborating) and asked us if we knew the significance of what he had drawn on the board. No one knew, and as such we moved on. However, I am now wondering. Attached is what he had drawn. To me it looks rather pointless. Is it supposed to signify a one way path (input----->output), or am I missing something?
