Abstract
A method compares an input value of the input signal stream with an output value of an integration function of a previous binary value to generate a new binary value based upon the comparison. The method then stores a plurality of successive binary values from the comparing step, and simulates an integration function for a plurality of possible bit sequences of the plurality of successive binary values. Finally, the method determines which sequence results in the smallest error between the input signal stream and the output value of the integration function, and uses the most significant bit of the determined sequence to adjust the integration function. A corresponding apparatus is also provided.
