Level Trigger:

1) The input signal is sampled when the clock signal is either HIGH or LOW.

2) It is sensitive to Glitches.

Example: Latch.

Edge Trigger:

1) The input signal is sampled at the RISING EDGE or FALLING EDGE of the clock signal.

2) It is not-sensitive to Glitches.

Example: Flipflop.

Difference between edge triggered and level triggered flipflops?

in level trigger mode, the input signal is sampled when the clock signal is either high or low whereas in edge trigger mode the input signal is sampled at rising or at the falling edge. lever triggering is sensitive to glitches whereas edge trigger is non sensitive.. example: latch for level trigger and flip-flop for edge trigger

Difference between positive edge trigger and negative edge trigger for flipflop?

A: it does not apply to only flip-flop but to all kinds of logic circuits where a [+] transition from a less negative to a more positive level occurs [-] and the other way around meaning a +/- transition must occurs to transfer states.

Level trigger and edge trigger?

Level triggering means the specified action occurs based on the steady state value of the input. An SR flip flop is an example of this - so long as S is true, the flip flop will stay set. Edge triggering, on the other hand, means the specified action occurs on the edge of the transistion of the input, either from low to high or from high to low. The clock input of a D flip flop is an example of this - once the event ocurrs, the input must go back to its prior state and then generate the triggering edge again. ANSWER: level triggering means when a certain level is reached the output will change states . ANSWER: Edge triggering means that the output will change state on a leading or falling input transition depending on the application. It has nothing to do with RS or set or reset if conditions are right.


What is edge detection?

Edge detection generally applies to a square wave signal, such as a clock pulse or a trigger pulse. Then the edge detection comes from either using the rising voltage, or the falling voltage of the signal (usually a square wave) to trigger the next event. Using the falling voltage implies a delay in the signal and the rising pulse to trigger an immediate `step` in the circuit.

What is the difference between an idiom and an idom?

"Idom" is not a word in English, so the difference is between a word and a non-word. An idiom is a phrase that cannot be understood unless you know the idiomatic meaning already. "On edge" is an example of an idiom because you are not literally standing on an edge - you are anxious or frustrated.
