Shift Registers

Q1: The group of bits 10110111 is serially shifted (right-most bit first) into an 8-bit parallel output shift register with an initial state 11110000. After two clock pulses, the register contains ________.

A 10110111

B 11110000

C 11111100

D 10111000

ANS:D - 11111100

10110111/11110000 -> Initial.

1011011/11111000 -> After 1st clk pulse.

101101/11111100 -> After 2nd clk pulse.

Finally the sol is 11111100.
