Design a Truth Table and logic gate circuit to detect overflow of a two's complement addition A+B C. Inputs are "SignA", "SignB", and "SignC". Output is "Overflow". In other words, the output (overflow) goes high when we experience a state that can never happen. Remember that a O represents a positive number and a 1 represents a negative. So can we ever get a negative value if we are adding 2 positive values? Similarly, can we ever get a positive value if we are adding 2 negative values?
