ABSTRACT:
A system and apparatus for encoding a set of input vector components by initiating a sequential search through a codebook memory to put out a series of associated error code vectors which can be compared in sequence over a period of time in order to select the minimum error code vector (best fit). A clocking-sequencing means enables an output latch to hold (after termination of the sequence period) the index number which represents the particular error code vector presently having the minimum distortion. Each new set of input vector components will be sequenced to search for the minimum error code vector (and index) for that particular set of input vector components.
