도움말 항목

  • Quantization

    Quantize data to improve signal sampling efficiency in communications systems.

  • Differential Pulse Code Modulation

    Use DPCM as a predictive quantization method.

  • Compand a Signal

    Make µ-law or A-law compressor and expander calculations.

  • Huffman Coding

    Compress data so that no codeword is a prefix of any other codeword in the dictionary by using Huffman coding and decoding.

  • Arithmetic Coding

    Compress data from sources with a small alphabet by using arithmetic coding and decoding.
