针对离散信号的傅里叶变换与模拟信号的傅里叶变换之间关系,介绍了一种与教材不同,既简单又易于理解的推导方法;并对教材的“实际隐含了T=1的假设”提出不同的见解。
Aiming at the relationship between the Fourier transform of discrete signal and the Fourier transform of analog signal, a new derivation method which is different from the textbook is introduced, which is simple and easy to understand. Hypothesis "put forward different opinions.
