Answer / isuru dhananjaya senevirathne

An edge triggered storage device responds to the data only during a
narrow time window surrounding the active clock edge. The width of the
window is specified by the setup and hold time specs of the device. A
gated device responds to the data during the entire time that
the clock is high (or low).

Designing with edge triggered devices is generally easier (that is their
main advantage) and they are less vulnerable to noise, but edge
triggered devices are more costly. Whereas you can build a
level-triggered storage element with a single latch you typically need
two latches, in a master-slave arrangement, to implement an
edge-triggered storage element.=20

Sometimes your design may not be able to afford the one clock period
delay that the edge triggered device introduces, and a level triggered
device may then be more appropriate.

Answer / san-j

Edge triggered devices only response at a rising edge or/and falling edge of a clock signal. But in enable gated devices response during the level triggered states. Both types are important and there are different applications also in engineering applications.
