Correct Answer : Option (D) : Ring counter
Explanation : A series of equally spaced timing pulses may be easily generated in clock shifts. In the Ring counter, the output of the last flip flops is connected to the first flip flop input, i.e., the ring counter is the cascaded connection of flip flops. It means feedback of the output of the flip-flops is fed to the input of the same flip-flop. It generates equally spaced timing pulses.
