  1. One is to use fourier transformation to convert the source signal from time domain to frequency domain and to discard high frequency harmonious components upwards of 19 ( gb / t14953 - 93 d5. 3 demanding ), then to have static huffman coding to the quantized char array which is composed of reserved direct current component and basic wave and each high frequency " s amplitudes and angles. the other is to use discrete wavelet transformation to convert the source signal from time domain to frequency domain and to set the high frequency coefficients that its absolute value is smaller than the given threshold to zero, then to have dynamic huffman coding to the quantized char array which is composed of multiple, wavelet ' s level, datum length, low frequency coefficients and reserved high frequency coefficients. mass simulinks and analyses under the two circumstances have done to show that data compression ratio is small and the relative error is also small and within the permission of engineering and the compression problem can be solved in theory of measured datum of power system

    第一種情況的壓縮方法為：採用傳統的傅立葉變換把原始信號從時間域變換到頻率域，舍棄20次及其以上的高次諧波成分（保證了gb / t14953 ? 93d5 . 3要求） ，然後對保留的直流分量、基波和各次諧波的幅值和相角數據量化后和量化時分別乘以的倍數系數構成一個數組，以字元形式保存，採用靜態huffman編碼對變換數據進行壓縮；採用離散小波變換把原始信號從時間域變換到頻率域，然後對分解得到的高頻系數進行閾值量化處理，對乘以的倍數系數、小波變換的階數、小波變換后的低頻、各級高頻以及原始數據長度、量化后的低頻系數以及保留的高頻系數大小、位置構成一個數組，以字元形式保存，採用動態huffman編碼對這個文件進行壓縮。
  2. Information technology - international standardized profiles fvt3nn - virtual terminal basic class - register of attribute assignment type definitions - fvt322 - font assignment type no. 2

    信息技術.國際標準數據區fvt3nn .虛擬終端基本級別.屬性賦值類型定義寄存器. fvt322 . 2號字形賦值類型
  3. This article uses cpld technology to improve the hardware integration degree so as to ensure the high system reliability ; it applies digital signal process technology to producing and recognizing large volume ditigal voice signals in switch systems ; it replaces the old - used special voice signal process chips, thus lowers the cost, improves the quality ; it uses high quality common pc 104 units to complete the main processor tasks, which greatly improves the signal processing capability in the digital switch systems, and provides a great convinence for future technology upgrade as well ; in system archtecture, we exploit modular design technique on client ports and repeater ports, which gains more reliability and easy maintenance

    本文主要採用了cpld技術提高硬體的集成度以保證系統的高可靠性：用數字信號處理技術完成交換系統中大量的語音信號的產生和識別，代替以前的專用語音信號處理晶元，降低了成本，提高了性能：用高性能的通用pc104單元完成主處理機的工作，大大提高了數字交換系統的信息處理能力，並為今後的技術升級提供了方便：在系統結構上對用戶埠和中繼埠採用模塊化設計，性能可靠，維護方便。
  4. Digital information processing and blur intelligent identifying technology, introduced imported ic and transducer, with test and analysis par, the magnetic signal is more precise and reliable, it ' s very effective for all kinds of false coin : especially the false coin with magnetism

    數字化信息處理和模糊智能識別技術，採用進口集成電路及傳感齊，使用檢測和分析票面，磁性信號更精確，更可靠，針對各種* * * ：特別是帶有磁性的超級* * * ，非常有效。
