翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Tandem signaling ： ウィキペディア英語版 Tandem signaling Tandem signaling is the two-step conversion of a digital signal into an analog signal, followed by the reverse conversion. While there is a universal standard for analog signal transmission, digital signals may employ a variety of sampling rates and encoding methods (codecs). Any differences in sampling rate or encoding between transmitter and receiver introduces errors or artifacts in the resulting signal. When speech is being transmitted, as in audio telephone calls, tandem signaling may produce unintelligible results. Tandem signaling is an important evaluation criterion in the evaluation of speech coders. ==Background== Mobile telephones use digital signals, while land lines terminate in analog signal systems. For historical reasons, mobile phone calls that cross network/carrier boundaries use an analog network backbone, and are converted from digital to analog signals on one network and converted back to digital signals on the receiving network. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tandem signaling」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
