摘要
分析了连续信号抽样变成抽样序列频谱分析与实际电路模型不一致 ,而理论上的频谱分析导出了对实际电路模型频谱分析适用的原因 给出了实际电路抽样连续信号完成抽样序列的频谱分析方法 ,最后根据这一方法完成了有限长离散傅里叶正。
Two reasons why the spectral analysis for sequence of samples of continuous-time signal is not in keeping with the actual circuit model and why theoretical spectral analysis is suitable for the actual circuit model are analysed. The spectral analysis method used for the sequence of samples resulted from actual circuits is presented. Based on the method, the discreted-time Fourier transform of finite sequence and its inverse transform are finished here
