  1. Delay line oscillator is composed of broadband amprifer adjustable attenuator and saw sensor device. after output signal of delay line oscillator is smoothed, it mixes with 109mhz local oscillation signal. its differential frequency signal is smoothed by low - pass filter trimmed by shaping circuit and processed by digital processing circuit

    延遲線放大、可調衰減和聲表面波質量傳感件構成。延遲線輸出信號經濾波后與109mhz的本機晶體輸出信號相混,通過低通濾波取其差,並經整形後由數字信號處理電路處理。
  2. Section ii describes the design approach and implementation of speech module on mcf5249 coldfire core. the speech codec optimizes g. 729a codes and added voice activity detection of g. 729b to save bandwidth ; the implementation of acoustic echo cancellation uses nlms algorithm and it can reduce echo though designing adaptive fir filter and speech detector ; the dtmf and cpt generate signal using two second order digital sinusoidal oscillators and detect signal by picking up the frequency information. but only get the frequency information is not enough in cpt detector, this thesis introduces a method

    其中對語音編解碼的設計採用優化g . 729a代碼達到設計要求,並在此基礎上加入g . 729b的靜音檢測模塊,以進一步降低網路傳輸;對回聲消除的設計採用nlms演算法,通過設計自適應fir濾波和語音檢測達到回聲消除目的;對雙音多設計,信號發生端採用構造靜態參數表並通過二階正弦產生信號,信號檢測端提取率信息以檢測信號;對呼叫進程音設計,除了類似雙音多的信號發生及率檢測設計外,還需要檢測信號持續時間,作者設計了一種基於匹配狀態表的方法以檢測信號持續時間。
