Construct a 2-bit binary ripple carry adder/subtractor with inputs A(A1, A0) and B(B1, B0) bydoing the following.1 Derive a truth table for a 1-bit full adder.2)  Develop optimized functions for the 1-bit full adder. Derive a truth table for a 1-bit half adder.4)  Develop optimized functions for the 1-bit half adder.5)Using the above adder(s) as the basic components and other standard gates construct a 2-bitbinary adder/subtractor. Must label each input, output and internal signal with proper name.

(Civil eng.) The maximum load that can be placed at the end of a symmetrical wooden beam, such as the rectangular beam shown in Figure 2.20, can be calculated as the following: L=S1dc L is the maximum weight in lbs of the load placed on the beam. S is the stress in lbs/in2. I is the beam’s rectangular moment of inertia in units of in4. d is the distance in inches that the load is placed from the fixed end of the beam (the “moment arm”). c is one-half the height in inches of the symmetrical beam. For a 2” × 4” wooden beam, the rectangular moment of inertia is given by this formula: I=baseheight3=12=24312=10.674 c=(4in)=2in a. Using this information, design, write, compile, and run a C++ program that computes the maximum load in lbs that can be placed at the end of an 8-foot 24 wooden beam so that the stress on the fixed end is 3000lb/in2. b. Use the program developed in Exercise 9a to determine the maximum load in lbs that can be placed at the end of a 3” × 6” wooden beam so that the stress on the fixed end is 3000lb/in2.

If 2 bits of a byte are in error when the byte is read from ECC memory, can ECC detect the error? Can it fix the error?
