QT是目前Linux上最知名的窗口环境系统
QT是目前Linux上最知名的窗口环境系统，除了桌上型电脑之外，PDA上的Linux系统也大都是以QT当作窗口环境。 目前QT在Linux PDA上必须安装的程序包括QT/Embedded与QT/Pa...
DFT进行频谱分析时的三种现象 1、混叠：对连续信号采样
DFT进行频谱分析时的三种现象 1、混叠：对连续信号采样，要求连续信号是带限的，采样频率要足够高。Fs应满足Nyquist采样定理才不产生混叠。 采样前加低通滤波器防混叠 2、频谱泄漏：D...

采样率小于一个连续时间信号最大频率的2倍时就叫undersampling
采样率小于一个连续时间信号最大频率的2倍时就叫undersampling，欠采样，根据抽样定理，当fs>=2fmax，也就是oversampling，过采样时，数字信号才能重建成原来的模拟信号，...
