flow control procedure

A procedure for controlling the rate of transfer of data among elements of a network, e.g., between a DTE (data terminal equipment) and a data switching exchange network, to prevent overload.

flowchart

A graphical representation in which symbols are used to represent such things as operations, data, flow direction, and equipment, for the definition, analysis, or solution of a problem. Synonym flow diagram.

flowline

On a flowchart, a line that (a) has an indicated direction, (b) represents a connection between other symbols, and (c) indicates the sequence of operations or the transfer of control.

FLUTE

File Delivery over Unidirectional Transport

flutter

Rapid variation of signal parameters, such as amplitude, phase, and frequency.
Note: Examples of flutter are (a) rapid variations in received signal levels, such as variations that may be caused by atmospheric disturbances, antenna movements in a high wind, or interaction with other signals, (b) in radio propagation, a phenomenon in which nearly all radio signals that are usually reflected… (Read More →)

flywheel effect

In an oscillator, the continuation of oscillations after removal of the control stimulus.
Note 1: The flywheel effect is usually caused by interacting inductive and capacitive circuits in the oscillator.
Note 2: The flywheel effect may be desirable, such as in phase-locked loops used in synchronous systems, or undesirable, such as in voltage-controlled oscillators. Synonym flywheeling.
