Abstract
A binary encoder for vector quantization is provided which comprises a plurality of identical two-level branch selectors connected in a turnaround cascade pipeline array. The upper levels of the two-level selectors are connected in series and the first selector receives a formatted digital data vector input. The upper level of last selector has its output connected to its own lower level input and the outputs of the lower level selectors are connected in series so that the last lower level selector in the turnaround cascade resides in the first two level selector. The output of the last lower level selector provides a desired compressed data vector output.
