**What is jitter?** Jitter is *any deviation in the signal pulses of a high-frequency digital signal.* > **What three characteristics of a signal can experience jitter?** > The three characteristics of a signal that can experience jitter are: > 1. Amplitude. > 2. Phase timing. > 3. Width of the signal pulse. > [!example] Examples of the effects of jitter > * A display monitor flickering. > * The ability of the processor in a desktop or server to perform as intended. > * Clicks or other undesired effects in audio signals. > * Loss of transmitted data between network devices. **What is the amount of allowable jitter dependent on?** The amount of allowable jitter is dependent on *the application.* **What is jitter in Internet Protocol (IP) networks?** Jitter in IP networks is *the variation in latency on a packet flow between two systems.* > **What are three causes of jitter in Internet Protocol (IP) networks?** > Three causes of jitter in IP networks include: > 1. Network congestion. > 2. Timing drift. > 3. Route changes. ...
