Exercise 3 Let A be a binary number with two bits a1 and a2. Design an incrementer where the input is A and the output is B = A 1 encoded as a 2-bit result (b1 and b2) and a carry bit r. 1. Create the truth table for the incrementer. 2. Provide the simplified expressions for the results. 3. Create the logic diagram for the incrementer. Exercise 4 Consider a binary information of 3 bits (a0, a1, and
