The D- flip flop has only one input terminal. The D flip flop may be obtained from an S-R flip flop by just putting one inverter between S & R terminals. In this figure it is positive edge triggered flip flop. negative edge triggered D flip flop operates in the same way as positive edge triggered except that the change of state takes place at the negative on going edge of the clock pulse.
