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:
“I prefer “you” in the plural, I want “you,”
You must come to me, all golden and pale
Like the dew and the air.
And then I start getting this feeling of exaltation.”
—John Ashbery (b. 1927)
“The experience of a sense of guilt for wrong-doing is necessary for the development of self-control. The guilt feelings will later serve as a warning signal which the child can produce himself when an impulse to repeat the naughty act comes over him. When the child can produce his on warning signals, independent of the actual presence of the adult, he is on the way to developing a conscience.”
—Selma H. Fraiberg (20th century)
