Question #$1$: $10$ points

For the shift register shown below, assume that $Q0=1,Q1=0,Q2=1.$ Assume also that $Do=1,D1=0,D2=0,$ and Serial input $=1.$

What are the values of Q$0,$ Q$1,$ Q$2$ after the next positive edge clock if

a$.$ Shift $=0$ and Load$=0$

Q$0=$ Q$1=$ Q$2=$

b$.$ Shift $=0$ and Load $=1$

Q$0=$ Q$1=$ Q$2=$

c$.$ Shift $=1$ and Load$=0$

$Q0=,Q1=$

Q$2=$

d$.$ Shift $=1$ and Load $=1$

Q$0=$

Q$1=$

Q$2=$
