Glitch is a pulse noise of different origin.
It’s often a reason for logical systems failure. Typical instances of glitch are:
- Reflections – appear in mismatched lines, the signal part is reflected from the receiving device back to the line after some delay.
- Noise pickup – induced signal appearance in a very closely located neighbor bus.
- Jump on the ground – local temporary ground level sift (and therefore - threshold voltage) caused by the current surge into the ground bus as a result of either simultaneous operation of many gates connected to the same ground bus or the operation of the gate to inductive load.
