1. A method for converting an analog signal to a digital signal, comprising:
- receiving an analog signal;
measuring a voltage of the analog signal with respect to a sampling point;
selecting, based on the voltage measured, a digital code comprising a plurality of binary bits;
inverting substantially one half of the plurality of binary bits of the digital code without consideration of the state of the binary bits to produce a modified digital code to represent the analog signal at the sampling point.

Abstract
A method and system for converting a digital code. A digital signal is encoded to have a digital code having multiple binary bits. Substantially one half of the binary bits of the digital code is inverted to produce a modified digital code to reduce digital noise associated with the digital code.
