A bidirectional 4-bit shift register is storing the nibble 1110. Its input is LOW. The nibble 0111 is waiting to be entered on the serial data-input line. After two clock pulses, the shift register is storing ________.-A-1110B-0111C-1000D-1001-D-1001

Question

A bidirectional 4-bit shift register is storing the nibble 1110. Its  input is LOW. The nibble 0111 is waiting to be entered on the serial data-input line. After two clock pulses, the shift register is storing ________.-A-1110B-0111C-1000D-1001-D-1001

APTITUDE CRACK · Accepted Answer

D 1001 Stored nibble : waitin nibble. Initially 1110 : 0111. 1st pulse 1100 : 111. 2nd pulse 1001 : 11. The final answer after 2nd clk pulse is 1001.
