摘要：Problem to be solved: to reduce the circuit size and the delay by suppressingthe amount of calculation processing while maintaining the efficiency of the

communication line by maintaining constant bit rate after encoding. Encoding apparatusAsample value that constitutes part of the discrete time signal isAn encoding apparatus

for encoding a coded bit string having a fixed length;A division part which divides thesample value into positive and negative bits and the lower bit part, andA variable lengthcoding unit which outputs a code by performing variable length coding processing for theabove upper bit portion andIf the total length of the positive and negative bits, the signand the lower bit portion exceeds the predetermined lengthA rounding processingsection for rounding the lower bit portion so that the total length is equal to thepredetermined lengthThe combination of the positive and negative codes, the sign, andthe lower bit portion is provided with a coupling portion for outputting the coded bitstring.Diagram
