A '''Pulse transition detector''' is used in [[Flip-flop (electronics)|flip flops]] in order to achieve edge triggering in the [[circuit]]. It merely converts the clocks[[clock]]'s [[Clock edge|rising edge]] to a very narrow pulse.

The PTD consists of a delay gate (which delays the [[clock signal]]) and the clock signal itself passed through a [[NAND gate]] and then inverted.

The benefit of edge triggering is that it removes the problems of zeroes and ones catching associated with pulse triggered flipflops (eg. [[Master-slave (technology)|master slave]] flip flops).
