Consider the following truth table for 3 logic operations NO, NAND, and XOR  on single bit a and b.     Also consider the following 1-bit ALU that performs AND, OR, and addition on a and b.                           Note that one can select between three values using the Operation select line to the Result multiplexor. Assume that the Ainvert and Binvert signals can be asserted or de-asserted and that the CarryIn signal can be de-asserted or taken from the CarryOut of the preceding 1-bit ALU.  Pick a set of control signals for each Boolean logic operator. Some will go unused.
