ABSTRACT:
Measuring a signal includes setting a gain numerator of a gain value and setting a gain denominator of the gain value, where the gain value is a ratio of the gain numerator to the gain denominator. An input signal is received and adjusted in accordance to the gain value to yield an output signal. The input signal is determined using the output signal and a reciprocal of the gain value, where the reciprocal is a ratio of the gain denominator to the gain numerator.
