摘要
实现了处理宽频带信号的自适应增量调制(ADM)及解调系统,并对该系统进行了一系列研究,实验结果与理论分析基本一致,系统在10Hz~10kHz工作带宽范围内具有良好的响应能力,其采样率、步长数和记忆比特均可变,适合不同条件下的应用要求。本研究在音乐信号处理实验上获得了满意的结果,对于语音、地震等信号的处理亦具有广泛的应用前景。
A adaptive delta modulation(ADM) and demodulation system which can process the broadband signals is realized, and a series of studies for the system is given. The experimental results are closed to the theory analysis. In the working band 10Hz~10kHz of the system, it has a good ability of response. Its sampling rate, step nuamber and the number of remembering bits can be adjusted for various applications. For example, it can process the signals of speech, music, seismic data and so on.
