Before revision: Signal edges shown in rectangular pulse amplitude modulation with polar non-return-to-zero, inverted coding waveform In electronics, a signal edge is a transition of a digital signal from low to high (0 to 1) or from high to low (1 to 0) : A rising edge (or positive edge) is the low-to-high transition.
