(b) Complete the following table that adds three one-bit numbers (a+b+c) together, for all combinations of a,b, and c. One of the rows is shown to clarify the format: (c) Looking at your table above, describe an automated way to add three 1-bit numbers together. For instance, if just one of a or b or c is a 1 , what should the output be? You can use English, or code (or Verilog!) to answer. (d) Can you come up with an equation for each of the two bits in the output ( a+ b+c ) that depends on a,b, and c and doesn't use the addition operation
