What is the clock pulse? Edge triggered and Level triggered in tamil

Edge Triggering and Level Triggering
Digital circuits employ edge triggering and level triggering as two different types of triggering methods to start a signal transition from one state to another. Both are essential components of digital electronics and are used to speed up data flow and regulate the timing of events in the system.

Edge Triggering:
An example of a triggering mechanism that is based on the recognition of a change in the signal level is edge triggering. It is employed whenever it is important to identify the change in the input signal’s condition from low to high or high to low. Edge triggering is frequently employed in synchronous circuits, such as flip-flops and counters, and is especially beneficial in situations when exact timing is necessary.

In edge triggering, the input signal’s sharp edge, which is picked up by the circuit’s clock signal, triggers the signal change. The trigger edge is this abrupt edge, and depending on how the circuit is constructed, it may be rising or dropping. The circuit reacts by switching the output signal to the opposing state when it detects the trigger edge.

Level Triggering:
On the other hand, level triggering is a category of triggering mechanism that is based on the detection of a particular signal level. It is applied when detecting the input signal level at a specific moment rather than a change in state is required. In applications like data acquisition and control systems, where continuous monitoring of an input signal is necessary, level triggering is frequently utilized.

Level triggering involves continuously monitoring the input signal and activating the output signal when the input signal reaches a predetermined level. Depending on the circuit’s design, this level may be high or low. As long as the input signal is at or above the trigger level, the output signal is in the triggered condition.
