Editing Pulse (signal processing) (section)

===Rectangular pulse===
These can be found in [[pulse wave]]s, [[Square wave (waveform)|square wave]]s, [[boxcar function]]s, and [[rectangular function]]s. In digital signals the up and down transitions between high and low levels are called the rising [[signal edge|edge]] and the falling edge.  In digital systems the detection of these sides or action taken in response is termed edge-triggered, rising or falling depending on which side of rectangular pulse.  A [[digital timing diagram]] is an example of a well-ordered collection of rectangular pulses.
