Flip flop is edge triggered device
Chat with our AI personalities
An SR flip-flop can be converted into an edge triggered flip-flop with preset and clear inputs by adding the clock and the asynchronous inputs.
a group of flip-flops sensitive to pulse duration is called latch whereas a group of flip-flops sensitive to pulse transition is called a register.
flipflop is edge triggering and latch is level triggering
consists of two r-s flip-flops wherein clock of the first is negated and applied to the second.it is used to avoid the problem of race-around condition by making sure that the first flip-flop is triggered during the positive going edge and the second during the negative edge of the clock pulse.
In a master-slave flip-flip arrangement, the master flip-flop determines its state on one clock edge, while the slave flip-flop determines its state on the following clock edge. This way, the end-to-end output does not ever change on any one clock edge, so no race condition is possible.
