Q1. Binary, Sign-Magnitude and Two's Complement Explained.
Binary, Sign-Magnitude and Two's Complement are three different methods of representing numbers. As we will show in this discussion, Binary is only good for representing positive (Unsigned) numbers.....Sign-Magnitude has a number of problems and that Two's Complement is the best method to represent Signed numbers. . .

Q2. Math Equations for Converting ADC Data to voltage.
The math equations used to convert the "raw" data that is provided by the Analog-to-Digital Conversion (ADC) to the actual units you are measuring (normally voltage) depends upon five factors. . . . . (select above link to read entire document)
