1．了解数字信号处理系统的一般构成；
2．掌握奈奎斯特抽样定理。
为方便实现，实验中更换了一种表现形式，即抽样频率固定（10KHz），通过改变输入模拟信号的频率来展示低通抽样定理。我们可以通过研究抽样频率和模拟信号最高频率分量的频率之间的关系，来验证低通抽样定理。-1. Understanding digital signal processing system of the general composition; 2. Master Nyquist Sampling Theorem. To facilitate the realization of the experiment to replace a form of expression, that is, fixed sampling frequency (10KHz). By changing the input signal frequency to demonstrate low-pass sampling theorem. We can, through research and sampling frequency of the highest frequency analog signal frequency components of the relationship between to verify low-pass sampling theorem.
