PCM System Block Diagram

Figure 14—19 shows how PCM is applied to encode and recover a voice signal. The process begins with the voice signal being passed through a low-pass filter called an anti-aliasing filter. This filter removes any frequency components higher than f/2, to prevent aliasing distortion.

    圖14-19顯示,如何施加PCM以便編碼及回復語音訊號。這個過程開始時,語音訊號通過低通濾波器(稱為反假化濾波器)。這一濾波器移除任何高於f/2的頻率成份,以防止假化失真現象。

    PCM 系統結構圖

    在圖14—19 顯示出,PCM 是如何被應用輸入和恢復聲音信號。從過程中看出,剛開始聲音信號會通過低通過過濾器,稱anti-aliasing 過濾器。這種過濾器可去除所有頻率組分,比f/2更加高級,可防止突變的混淆現象。
