I have an assignment due for school, but this one question has been getting the best of my group-mate and I for about a week now. I am in no way asking you to solve the problem for me, but could you please make it a little bit simpler for us to understand.
Question: If the input and output bit patterns in the circuit below are interpreted as binary representations of numeric values, what operation does the circuit perform?
1) If we put in a set of ones and zeroes as input then determined what the output would be , then convert the input bit pattern and output pattern to decimal, then we could try to figure out what base 10 mathematical operation was performed. Although when this was tried, there seemed to be no simple correlation between the input and the output.
2) Assuming that the question is not looking for a mathematical operation , and is instead looking for a logical operation, we tried drawing up a truth table, then go stuck("Where do we go from here? ").
1) The question stated that the input and output bit patterns are binary representations of numeric values, we cant figure out why that is important , because when trying to do base ten arithmetic, it did not work.
2) Why did they put the '1' as an input?
3) assuming three inputs, how to you go about finding out what single logical operation is performed in the circuit.
