What is the Difference Between Edge and Level Triggering
The main difference between edge and level triggering is that in edge triggering, the output of the sequential circuit changes during the high voltage period or low voltage period while, in level triggering, the output of the sequential circuit changes during transits from the high voltage to low voltage or low voltage to high voltage.
In a sequential circuit, the output changes depending on the triggering. There are two types of triggering as edge and level triggering. There are two levels in a clock pulse or a signal. One is a high voltage (VH), and the other is low voltage (VL). Furthermore, these voltage levels help to determine the triggering type.
Edge triggering is a type of triggering that allows a circuit to become active at the positive edge or the negative edge of the clock signal. In contrast, level triggering is a type of triggering that allows a circuit to become active when the clock pulse is on a particular level.
In edge triggering, an event occurs at the rising edge or falling edge whereas, in level triggering, an event occurs during the high voltage level or low voltage level. Thus, this is the main difference between edge and level triggering.
Furthermore, another difference between edge and level triggering is that the flip flops work according to edge triggering, whereas Latches work according to level triggering.
In brief, there are two types of triggering in sequential circuits. The triggering results can change the output of the circuit. The main difference between edge and level triggering is that, in edge triggering, the output of the sequential circuit changes during the high voltage period or low voltage period while in level triggering, the output of the sequential circuit changes during transits from the high voltage to low voltage or low voltage to high voltage.
