This is a conceptual question. What I understand is that runt pulse is like a glitch but its amplitude is less than the main pulse's amplitude. If Im not wrong on this definition, below illustartes the difference:
Since I observe all of these kind of outputs time to time; can a very low hysteresis be the source of the problem by cosnidering the shapes of the pulse outputs? I can understand a Schmitt trigger with very low hysteresis can cause a glitch but I dont get if it can cause a runt pulse or other type of noisy outputs above. Is that possible? Or runt pulse's source should be searched some where else?
