Jitter
Jitter is any deviation in, or displacement of, the signal pulses in a high-frequency digital signal. The aberration can be in amplitude, phase timing, or the width of the signal pulse. Jitter is sometimes referred to as “packet delay variation,” or pdv. Controlling jitter is critical for a good online experience.
