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 V H , and the other is low voltage V L. Furthermore, these voltage levels help to determine the triggering type. What is Edge Triggering — Definition, Functionality 2. What is Level Triggering — Definition, Functionality 3. In a sequential circuit, if the output changes when the signal transits from a high level to a low level or from a low level to a high level, we call it edge triggering. Here, the edge that changes the voltage from low level to the high level is called rising edge positive edge.
And, the edge that changes the voltage from high level to the low level is called falling edge negative edge. I will visit your website frequently for Some most recent post.

On an , TRAP is a non-maskable interrupt normally used to handle errors such as a power failure. If it were level triggered, its code could never execute because it's an unmaskable interrupt. The handler would start executing when it became active, but it would still be active, so the handler would start executing, but it would still be active, so the handler would start executing, etc.
Therefore it has to be edge triggered. However, edge triggering is a problem when the line may have glitches. Glitches may cause the handler to be invoked multiple time as the line glitches. As a compromise, the TRAP works as if it is level triggered, except that it is only recognized when it has been low since the last time it was recognized.
That ensures that the TRAP handler is only invoked once. In level triggering the circuit will become active when the gating or clock pulse is on a particular level. In edge triggering the circuit becomes active at negative or positive edge of the clock signal. Python Javascript Linux Cheat sheet Contact. What does edge triggered and level triggered mean?
