Difference between
both.?
Latches..
 Latches are the building
blocks of sequential circuits.
 latches can be built from
gates.
 latch does not have a clock
signal.
Flip Flop..
 flip-flops are also the building
blocks of sequential circuits.
 Flip-flops can be built from
latches.
 A flip-flop always has a clock
Signal
 Both are same but there is a little difference between both.
