The second class cable ? suitable for more the earthing ? block time and more better insulated performa 第二類? ?用于接地故障時間更長的系統(tǒng)及對電纜絕緣性能要求較高的場合。
Moreover , the block time - recursive 2 - d rdgt algorithms and their unified parallel lattice structure implementation are extended from 1 - d rdgt case . three applications of the rdgts are investigated : gabor representation for transient signals via the rdgts , mnr fid signal enhancement via the oversampled gabor transforms , representation and approximation of time - varying systems via the rdgts . the experimental results show the efficiency and advantages of the rdgts in applications 研究了基于實值離散gabor變換的瞬變信號表示算法、基于過抽樣實值離散gabor變換的核磁共振fid信號增強算法以及基于實值離散gabor變換的線性時變系統(tǒng)表示與逼近方法,實驗結(jié)果驗證了實值離散gabor變換在應(yīng)用方面的優(yōu)越性和有效性。
Two block time - recursive algorithms are developed for the efficient and fast computation of the 1 - d rdgt coefficients and for the fast reconstruction of the original signal from the coefficients in both the critical sampling case and the oversampling case . the two algorithms are implemented respectively by a unified parallel lattice structure . and the computational complexity analysis and comparison show that the proposed algorithms provide a more efficient and faster method for the computation of the discrete gabor transforms 首先論證了一維rdgt系數(shù)求解算法和由變換系數(shù)重建原信號算法,不論是在臨界抽樣條件下還是在過抽樣條件下,都同樣具有塊時間遞歸特性,并提出了相應(yīng)的塊時間遞歸算法及其并行格型結(jié)構(gòu)實現(xiàn)方法,計算機模擬驗證了并行格型結(jié)構(gòu)實現(xiàn)的可行性,計算復(fù)雜性分析與比較也說明了rdgt塊時間遞歸算法的并行格型結(jié)構(gòu)在計算時間方面所具有的高速和高效性能。
