ABSTRACT:
An electronic circuit for quantizing vector signals is provided. The circuit compares input vectors with codebook entries that are representative of a vector space. Processors simultaneously compute the distance between the image vectors and the codebook entries. Selection circuitry is provided which compares the distance values and generates outputs which are representative of the codebook vector having the smallest distance and the distance itself.
