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:
“My interest in desperation lies only in that sometimes I find myself having become desperate. Very seldom do I start out that way. I can see of course that, in the abstract, thinking and all activity is rather desperate.”
—Willem De Kooning (b. 1904)
“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)
