ANSWER:Step 1 of 2
The size of the A/D converter is 12-bit, that is
The input range of converter is , therefore lower end of input voltage is and upper end of input voltage is .
The formula used to find the output voltage of A/D converter in decimal for binary offset condition is,
…… (1)
By substituting, and into above equation,
…… (2)
