Edge triggered flip flop are of two types

1. Positive edge triggered flip flop-In a pulse train when ever the input is changing its state from negative edge to positive edge then it will be considered as logic 1 otherwise it is 0

2. Negative edge triggered flip flop-same as above but reverse.

LEVEL TRIGGERED FLIP FLOP are two types

1. Positive level triggered flip flop-in a pulse train when ever the pulse is high then it will be logic 1 otherwise it is zero.

2. Negative level triggered flip flop-in a pulse train when ever the pulse is low then it will be logic 1 otherwise it is zero.
