  • Abstract
    A description is presented of an effective adaptive encoder, an adaptive differential pulse code modulation (ADPCM) encoder whose main part is a LMS adaptive predictor, and applications in vibration signal compression. Some simulation results are also presented and analyzed. The ADPCM encoder described has the advantage of adapting statistical variation of the input signal and can maintain a relatively high compression ratio in such situations. It is an effective method in vibration signal compression
