In telecommunication, a start signal is a signal that prepares a device to receive data or to perform a function.
In asynchronous serial communication, start signals are used at the beginning of a character that prepares the receiving device for the reception of the code elements.
A start signal is limited to one signal element usually having the duration of a unit interval.
Famous quotes containing the words start and/or signal:
“A young man is not a proper hearer of lectures on political science; for he is inexperienced in the actions that occur in life, but its discussions start from these and are about these; and, further, since he tends to follow his passions, his study will be vain and unprofitable, because the end that is aimed at is not knowledge but action. And it makes no difference whether he is young in years or youthful in character.”
—Aristotle (384–323 B.C.)
“A signal is comprehended if it serves to make us notice the object or situation it bespeaks. A symbol is understood when we conceive the idea it presents.”
—Susanne K. Langer (1895–1995)
