So i have this shift register
With the initial values of ABCD (1101)
And the question is, how will this change after 4 clock pulses.
As I understand it, this shift register goes shifting the values from left to right. My first guess was basically taking the the lsb and putting it in first place and repeating the procedure 4 times (4 clock pulses).
I would then get ABCD (1101)
This is not the correct answer though.
