Consider the $74$ HC $1954-$bit parallel shift register $($see the example on pp$.446-447$ in the textbook$).$

a$.$ Determine the waveforms for the $4$ Q outputs given the signals below. At each clock cycle, indicate the mode of operation of the shift register $($e$.$g$.,$ LD$,$ Set, Reset, CLR$,...).$

Note: You can printout the worksheet on the last page to answer this question. If you choose not to use the worksheet, be sure to redraw all the relevant waveforms so your answer is clear.

b$.$ Use two $74$HC$1954-$bit shift registers to create an $8-$bit shift register. Show all the required connections between the relevant pins on the two ICs.

You may print this worksheet to answer Question $1$ regarding the $74$ HC $1954-$bit parallel shift register.
