Edge-triggered storage element is called F-F, and level-triggered storage element is called latch. Some puls-triggered F-F is used in dynamic logic circuits so as to save transistor counts, where the internal state of the F-F is changed during the time interval of the pulse width.
in Edge triggered the state can change only in transition i.e. when voltage is going from high to low or low to high.
It depends which edge triggered f/f you have -ve edge triggered or +ve edge triggered.
A pulse can be generated by moving a swtch from Low to High then back to Low. So the pulse-triggered FF needs a complete pulse Low -High - Low. and edge triggered can be divided into two:
Positive edge triggered ---> Low to High transition.
Negative edge triggered ---> High to Low transition.
Can you please tell me what is difference between master slave flip flop and edge triggered flip-flop? I mean if master slave ff is pulse triggered then how to make edge triggered ff?
a master slave flip flop was develpd in order to solve the problem of logic race ocurring normally in edge triggered JK FFs..in a Master Slave ff a known time delay(equal to the width of one clock pulse) is introduced between the time that the ff responds to a clock pulse nd the time the response appears on the o/p..
Making a master Slave ff an edge triggerd ff would defeat its entire purpose..
