 Supriya Adhikary said: (Mar 31, 2013) Ring counter:-If the output of a shift register is fed back to the input. A ring counter results. The data pattern contained within the shift register will recirculate as long as clock pulses are applied. For example, the data pattern will repeat every four clock pulses in the figure below. However, we must load a data pattern. All 0's or all 1's doesn't count.
