VECTOR QUANTIZATION ENCODER AND VECTOR QUANTIZATION DECODER ABSTRACT OF THE DISCLOSURE A vector quantization encoder and a vector quantization decoder compresses and decompresses speech signals, etc. The encoder or decoder comprises a plurality of codebooks each controlling a plurality of indexed code vectors of a different frequency band. Each of the codebooks is provided with a synthesis filter for reproducing a signal wave shape based on a code vector provided by the corresponding codebook. The encoder or decoder further comprises an adder for computing a sum of signal wave shapes reproduced by the synthesis filters. This arrangement can reduce the memory size of each codebook used for an encoding or a decoding process and an amount of operations of the encoding or decoding process.
