做OFDM通信少不了频谱分析，基带信号DA后的频谱，以及基带数字上变频后的DA信号都要频谱分析。我觉得实做任何工程都是这样，先规定实施方案，然后仿真成功，再实际开发，不过也可以一边开发，一边仿真，开发结果要与仿真预期结果一致。 所以分析与仿真 ...

Specifications for analog-to-digital converters (ADCs) often include a fast Fourier transform (FFT) plot, such as the one shown in the figure, for a 12-bit ADC with a single-frequency input signal. In ...
