    shift register is Sequential circuit that is used to implement digital memory

    I made serial input serial output 4 bit shift register using D flip flop (for practice )

    table 1000 0100 0010 0001

    bit 1 shifting from left to right

    one d flip flop store one bit so I used 4 D flip flop for 4 bit shift register

    1) can anyone explain the operation of 4 flip flop means function table

    1000 0100 0010 0001

    1000 flip flop A store 1
    0100 flip flop B store 1
    0010 flip flop C store 1

    What do you actually want to understand, how the flip-flops work, or how the shift register works using flip-flops?
