D stand for direct whatever will be the data at f/f it will transfer to o/p and on next clock it will transfer to next f/f, data will transfer directly on changing clock, f/f will respond according to -ve edge triggered clk in the same manner.

An edge-triggered flip-flop changes states either at the positive edge (rising edge) or at the negative edge (falling edge) of the clock pulse on the control input. The three basic types are introduced here: S-R, J-K and D.

Point1:
FF is -ve edge triggered means the o/p will follow i/p only on transition of clock from 1 to 0.
It means that the o/p D=Qn=Qn-1 when clock changes from 1 to 0.
FF is -ve edge triggered means the o/p will follow i/p only on transition of clock from 1 to 0.
It means that the o/p D=Qn=Qn-1 when clock changes from 1 to 0.

By the truth table of D flip flop, we can observe that Q always depends on D.
Hence for every negative trigger pulse ,the logic at input D is shifted to Output Q.

In negative triggering D, FF when there is '-ve' edge th o/p takes the identical value of i/p D, while at other remains with the same value.

Q(n + 1) = D normally but in case -ve edge trigger Q(n) = D here FF will take i/o value which is there before apply -ve edge i/o.

This works out for me to get a clear cut idea about how particular matter or topic.
Thank you all.
Thank you all.

Can anyone tell me what's the relation between CLK triggering and output of the Off.

Negative edge triggered is created with the help of D-flip flop and D depends on Q.

d flip flop takes the -ve edge triggered if the input is low
