In communicaton the bandwidth is an important problem that we should consider, specially in wireless communication. in fact the fiber is mainly used in backbone networks, so it is essential to develop the low rating coding technology of voice. the arithmetic of melp is based on the model of lpc and use the form of mixed excitation. because it integrates the idea of multi - band, so it has the merit of lpc and mbe. it is a perfect coding scheme in low rating voice coding relatively
而melp語音壓縮編碼演算法是在線性預測編碼參數模型的基礎上，採用混合激勵的形式，並且結合了多帶的思想，因此它擁有線性預測編碼和多帶激勵的優點，是目前低速率語音編碼中一種比較理想的編碼方案，也是本文研究的重點。本論文通過研究melp的語音編解碼演算法的原理，對它的編解碼過程作了比較深入的研究，對其中的一些公式進行了理論推導，並作了模擬分析，最後研究了該演算法的c語言實現。 -
Today, liquid crystal, a new functional material, has been applied more and more widely. on the side of display, owing to stable frarne, absolute environmental protecting, save electric energy and no tire for user, liquid crystal display keeps ahead among the range of display. with the developing of the technology of liquid crystsl, lcd will must substitute for crt and become the chief in market. in additin, liquid crystsl light filers which have been used in optic communicatins and light information handling, emply th e technical of combining the birefringence of liquid crystsl and fabry - petrot - type cavity. they manifest a series of merit, such as narrow band wide, deterioration low, wide tuning domain, simple structure and low cost, so liquid crystal light filter draw attention of many country
現在，液晶作為一種新型功能材料越來越得到廣泛的應用，在電子顯示裝置中，液晶顯示器以其畫面平穩、真正安全環保、省電和使用者不易疲勞等優點領先於顯示器的行列中。隨著液晶技術的發展，液晶顯示器將取代crt顯示器逐步成為未來市場的主流。此外，應用於光通信和光信息處理中的電調諧液晶濾光片，採用液晶材料的雙折射和電光效應與傳統f - p腔相結合，表現出窄帶寬、低損耗、調諧范圍寬、驅動電壓低、結構簡單、低成本等一系列優點，而日益受到各國研究部門的關注。
