Starting from an initial value of R in Hex is 47 determine the sequence of binary values in R
after a logical shift-left, followed by a circular shift-right, followed by a logical shift-right and a
circular shift-left. explain through the proper diagrams.

As a designner you have to obtain results using resistors to follow equation :

R3 <- R1 + R2

What would be an appropriate circuit to do so and why


4 A hardware implementation is required for executing the following equations, draw proper diagrams to complete your results. [5 marks] 1- x+y+z+a.b : R3 <- R4-R5 2- a.c.b+d : R3 <- R4+R6
