In
electronics
, a
signal edge
is a transition of a
digital signal
from low to high or from high to low:
- A
rising edge
(or
positive edge
) is the low-to-high transition.
[1]
- A
falling edge
(or
negative edge
) is the high-to-low transition.

In the case of a
pulse
, which consists of two edges:
- The
leading edge
(or
front edge
) is the first edge of the pulse.
- The
trailing edge
(or
back edge
) is the second edge of the pulse.
