Re: What is the difference between a latch & flip-flop?
latch is a level sensitive component and flip-flop is an edge triggered component.
consider D-Latch,
if clock is high and D = 0, then Q will be '0'
if clock is low , whatever may be the D value , output will simply show the same existing value on Q
consider D-flipflop
if clock is at +ve edge i.e. raising edge , the value of D at that particular instant will be shown in o/p
otherwise existing value will be shown on Q
