WebUsing D-flip flops, design a 4-bit shift register with parallel load and two control inputs shift and load. The criteria is such that when shift = 1 the contents of the register is shifted by one position. New data are transferred into the register when load = 1 and shift = 0. If both inputs are zero, the contents of the register should not change.
