フィードフォワードシラビックコンパンダの混変調ひずみ試験結果

Abstract

Syllabic companders play the important role of improving speech quality over poor radio channels. The feed-forward syllabic compander, which is newly proposing to exclude feed-back loops from circuitry topology, is already shown to be superior in transient responses in addition to effectively reducing fading noise. In this paper, intermodulation is successfully tested in the feed-forward syllabic compander under CCITT G. 162 recommendation through both theoretical analysis and computer simulations.
