  2. Because the noise that affects radio signals is partly, but not completely, manifested in amplitude variations, wideband fm receivers are inherently less sensitive to noise

    因為影響到無線電信號的噪只是部分的,而不是整體出現于變化中,調頻寬頻的接收器自身對噪不夠敏感。
  3. The algorithm have the good one - way property, high sensitivity to initial values and good security due to the intrinsic characteristic of chaotic system and rijndael algorithm. the simulation experiment demonstrates the convenience and good hash performance ; 3 ) a new scheme of digital voice secure communication was proposed based on chaotic modulation without additional synchronization. the modulation sequence generated by chaotic logical mapping was used to encrypt the digital voice signal

    混沌系統和rijndael演算法的固有特點使該演算法具有較好的安全性、對初值有高度的敏感性以及較好的單向性能,並且易於實現,是一種有效的單向hash函數; 3 )研究了一種無需同步的基於混沌調制的數字語保密通信系統的方案,利用邏輯映射產生混沌調制序列,以該序列作為密碼對數字語進行加密處理,為了更好的隱匿信號特徵,混沌調制在小分解的基礎上,對不同的通道使用不同的參數進行,並借鑒混沌掩蓋對信息信號進行了限處理,使密文完全隨機化。
  4. In an am transmission the carrier wave is constant in frequency and varies in amplitude ( strength ) according to the sounds present at the microphone ; in fm the carrier is constant in amplitude and varies in frequency

    調的傳播中,其負載電頻率是恆定的,但(力度)隨著麥克風聲變化而變化;在調頻的傳播中,其負載電是恆定的,而頻率隨著麥克風聲的變化而變化。
  5. Drm is a technology aims to improve sound quality of am transmission below 30 mhz and to reduce interference common in medium wave environment. new compression technologies known as mpeg4 advanced audio coding ( aac ) and spectral band replication ( sbr ) are employed to offer sound quality comparable to that of fm transmission

    它是針對30mhz以下的調( am )廣播而設計,大大提高了質,並改善了中廣播較易受干擾的情況;系統採用最新的壓縮技術mpeg4advancedaudiocoding ( aac )和spectralbandreplication ( sbr ) ,質足可與fm廣播媲美。
