Questions about the timing diagram on the right:
G looks like a ramp shape that goes down. Does that mean voltage was a higher constant then went down to a lower one?
What are the boxes containing V1 and V2? If they are voltages why not just horizontal lines?
What are these XXXXX's between those boxes containing V1 and V2?
I've been googling d latch timing diagrams to figure out the above- haven't found it yet but did notice that alot of other d latch timing diagrams look like horizontal lines/box/square wave shapes
