Analog to Digital conversion (negative half cycle)

Hello all,

Im having trouble understand the concept of a negative binary output number (with regards to the conversion from analog to digital).

For example, lets say i want to perform an integration on a sign wave ( one period) the values should combine to equal zero.

So if i use a full adder / subtractor circuit (and some memory) i should be able to accomplish this, the problem i am having is that i do not know how negative values are represented in the analog to digital conversion.

Any help would be appreciated.

Thank you.
