Jitter. In electronics and telecommunications, jitter is the deviation from true periodicity of a presumably periodic signal, often in relation to a reference clock signal. In clock recovery applications it is called timing jitter. [1] Jitter is a significant, and usually undesired, factor in the design of almost all communications links .
Network performance refers to measures of service quality of a network as seen by the customer. There are many different ways to measure the performance of a network, as each network is different in nature and design. Performance can also be modeled and simulated instead of measured; one example of this is using state transition diagrams to ...
P50 (neuroscience) In electroencephalography, the P50 is an event related potential occurring approximately 50 ms after the presentation of a stimulus, usually an auditory click. [1] The P50 response is used to measure sensory gating, or the reduced neurophysiological response to redundant stimuli. Research has found an abnormal P50 suppression ...
Packet delay variation. In computer networking, packet delay variation ( PDV) is the difference in end-to-end one-way delay between selected packets in a flow with any lost packets being ignored. [1] The effect is sometimes referred to as packet jitter, although the definition is an imprecise fit.
On the other hand, if you are over the age of 50 and cannot perform this 10-second balance test, you could be at a higher risk of dying within a decade compared to your peers, according to 2022 ...
Paired-click paradigm. The paired-click paradigm is a common non-invasive technique used to measure sensory gating, a type of event-related potential. For normal sensory gating, if a person hears a pair of clicks within 500 ms of one another, the person will gate out the second click because it is perceived as being redundant.
Frequency counter. A frequency counter is an electronic instrument, or component of one, that is used for measuring frequency. Frequency counters usually measure the number of cycles of oscillation or pulses per second in a periodic electronic signal. Such an instrument is sometimes called a cymometer, particularly one of Chinese manufacture ...
A new study found that 20% of participants were unable to perform a 10-second single-leg balance test. Researchers suggest balance may be a stronger indicator of our overall health than ever ...
