Synchronous Signal Programming
In the wider software development community the word signal is sometimes used especially to denote synchronous events (sequences of samples, video frames, etc., with constant sample rate or frame rate) rather than asynchronous events, while the word event and data flow is often used for asynchronous event queues, but this is by no means universal. Especially in telecommunications, electrical engineering and signal processing, a digital signal is a sampled representation of an analog physical entity.
In telecommunications, the term signalling means asynchronous phone call metadata information exchange, for example of telephone numbers.
One application of synchronous signal programming is observer pattern.

Famous quotes containing the words signal and/or programming:
“By day thy warning ringing bell to sound its notes,
By night thy silent signal lamps to swing.”
—Walt Whitman (1819–1892)
“If there is a price to pay for the privilege of spending the early years of child rearing in the driver’s seat, it is our reluctance, our inability, to tolerate being demoted to the backseat. Spurred by our success in programming our children during the preschool years, we may find it difficult to forgo in later states the level of control that once afforded us so much satisfaction.”
—Melinda M. Marshall (20th century)
