<p>Amplitude-adapted vector quantizer for encoding and decoding signals highly efficiently. An average value is separated by an average value separating circuit (2) for a blocked input signal, and a tree search inner product vector is quantized by a tree search vector quantizer (6). The index data is cut short depending upon the amplitude of a vector that is detected in order to cut short the amount of data to be transmitted.</p> |
