1. A method for searching for an optimal codevector from a plurality of codevectors in a codebook for data modeling of input signals to a data processing system, including a system for processing speech signals, the optimal codevector having a minimum weighted distance to a given vector, the codevectors comprising a plurality of components, the method comprising:

  • determining, for an input signal to a processing system to convert the input signal from an analog representation to a digital representation, a partial distance between a current vector component of a current codevector and of a corresponding component of the given vector;

    comparing the partial distance to a saved renormalized minimum partial distance; and

    proceeding to a next codevector when the saved renormalized minimum partial distance is smaller than the partial distance, whereby an optimal representation of the input signal as a digital signal in the processing system is efficiently achieved.
