Abstract
An input signal sample is converted, i.e., quantized, from a first digital code to a second digital code by combining an array of stored differential quantizer decision levels with the input signal sample to obtain an array of partial sum signal values. The signs of the partial sum signal values are algebraically summed and the result is used to obtain the quantizer interval that the input signal sample falls in.
