色度副載波再生器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Secondly, optical nodes usually do not possess the ability of wavelength interchange for the restriction of cost and technology, optical network brings out so - called wavelength continuity constraint because connection must be established on the path that be carried by the same wavelength between source and destination nodes
再者，波長轉換技術和成本限制使得網路節點一般沒有波長轉換能力，源目的節點間的通信連接必須始終承載在同一波長通道上，產生了所謂的波長連續性限制。
