lookahead logic was 4 bits. Now assume that the span of the
lookahead logic increases to 6 bits. Show the block diagram for a
32-bit adder similar to figure 9.5 in the text and compute what the
total gate delay is to c32 and s31 .

Derive the boolean expression for the output carry C4 for a 4-bit Carry Looka head Adder. Explain detail derivation steps. Add two numbers A=1110 and B=1011 with input carry C0 = 0 using Carry Lookahead Adder. Determine value of C4, C3, C2, C1 (use the expression derived in Q2) and S4, S3, S2, S1. Determine the overflow bit which is EXOR of carry going into MSB bit and carry coming from MSB bit i.e C4⊕C3.

Understand how to find the equation of motion of a particle undergoing uniform circular motion. Consider a particle--the small red block in the figure--that is constrained to move in a circle of radius R. We can specify its position solely by θ(t), the angle that the vector from the origin to the block makes with our chosen reference axis at time t. Following the standard conventions we measure θ(t) in the counterclockwise direction from the positive x axis. (Figure 1)...
