John : Before we start,  you might read it first.  https://chihaukam.blogspot.com/2026/01/john-if-my-career-is-professor-of.html?m=1.

.

Me: Ok.

.

John: See the 1st picture.  Both width and amplitude of a pulse are floating.  Yet, they must have 2 edges,  the falling and rising edge.  So, we can determine the width and position of it.

.

Me: Yes,

.

John : Thereby, we can generate a signal of Clock easily.

.

Me: Ok.

.

John : See the 2nd picture. When the signal of Clock enter a flip flop, the Q of this fip flop isn't perfect.

.

Me: Why isn't it "perfect" ?

.

John : There're plenty carrier waves. At Q, there's feedback of course. Yet, the direction of "current" of Q isn't too "unilateral". 

.

Me: Then, the output of Q isn't very uni-directional. 

.

John : Yes, it isn't. In another words,  the Clock's signal isn't "Clean" enough.
