I need help with this question from some work I am doing. I am attaching a picture (which is included at the bottom of this post) of it as well as typing the question out in case some of it is too blurry to read (Note: but what I am typing out follows what is in the attached picture word for word as you\'ll see below. Thank you.): 4.) The block diagram of a bidirectional shift register is given below. This register is controlled by a 2-bit code (SL, SR) with the operations performed listed in the table below. (Note: Please see the 1st attached image for the diagram and table the above question references to.) Manually simulate the register for 8 clock cycles with the initial contents and inputs as given in the simulation table below. The results due to any given line of the table are to appear on the following line due to the positive clock edge triggering of the register. (Note: Again, see attached 2nd image to see the table referenced in the question above)
