带通采样特点和仿真数字信号处理首先要把模拟信号变换为数字信号, 最常用的方法是采样, 奈奎斯特定律要求采样频率大于等于信号最

高频率的两倍, 对中心频率较高而频带较窄的信号使用奈奎斯特定律, 会造成采样频率很高同时有很多频段空白-Bandpass sampling characteristics and simulation of digital signal processing is first of all necessary for converting an analog signal into a digital signal, the most commonly used method is sampled, the Nyquist criterion requires that the sampling frequency is greater than or equal to twice the highest signal frequency, the higher center frequency band The narrower signal using the Nyquist criterion, will result in high sampling frequency at the same time there are a lot of band gaps
