    本文首先介紹了相關的軟體無線電理論；然後完成了包括數據格式，調制方式，糾錯碼方式，交織器和擾碼器等部分的中頻數據機通道設計；接著著重介紹了系統中使用的音頻壓縮演算法cvsd （連續可變斜率增量調制）的原理和實現，以及作為前向糾錯碼的卷積碼編碼理論和編解碼的高效實現。
  3. The electrical structure and mechanical structure of the non - ripple torque control system of brushless motor is almost the same as that of the control system of conventional brushless motor. the difference is that the non - ripple torque control system of brushless motor has a incremental encoder which the control system of conventional brushless motor has not, which results in a great change of control method

    永磁無刷電機無脈動轉距調速系統與傳統無刷電機調速系統在電磁、機械結構上基本一樣，所不同的是它在傳統無刷機控制系統的基礎上增加了一個增量式編碼盤，從而導致其控制方法有了比較大的改變。
  4. We made an improvement in overcoming the defects in speech signal adaptive delta modulation ( abbr. adm ), such as slope overloading and grain noise. in this method, numerical sliding average filtering was used for filtering decoding speech signal. experiments and analyses indicate that the method makes waveforms in good agreement between the decoding of adm and the original pulse coding modulation ( abbr. pcm ) signal, and considerably improves, the playback speech quality in naturalness, legibility and under standability

    針對語音信號自適應增量調制（ adm ）方式中斜率過載和顆粒噪聲缺點，提出了一種改進方法，它利用滑動平均方法對解碼后的信號進行數字濾波.試驗和分析表明，該方法使解碼后的信號波形與原脈沖編碼調制（ pcm ）波形具有很好的一致性，使再生語音質量在自然度、清晰度和可懂度方面比改進前均有較大提高
  5. Delta modulation code

    增量調制編碼
  6. Cvsd （ continuous variable slope delta modulation ） voice coding enables operation at high bit - error rates
