中文摘要：

时域有限的小波准滤波可避免准滤波实现中因逼近而产生的噪声；小波采样能处理带域无限的信号而完全地重构信号，因而适合处理小波准滤波输出的信号。本项目结合小波准滤波和小波采样的特点，并采用低比特量子化器（SIGMA-DELTA量子化器）构建新一代基于小波的A/D转化器。因小波准滤波-小波采样具高精度，易实现等特点，而低比特量子化具稳定，易实现等特点，该A/D转换器具高精度，稳定和易实现等优点。本项目的研究包括构造使准滤波噪声最小的时域有限小波滤波器并进行分析模拟测试；研究小波任意非均匀采样和任意采样率的超采样的信号重构方法并进行分析模拟测试；在分析一阶量子化器的基础上构造高阶SIGMA-DELTA量子化器并进行分析模拟测试。最后建立基于小波的A/D转换器的模拟系统。
