摘要
文章研究了数字信号传输的模型,较详细地讨论了升余弦频谱过渡特性滤波器的数学机理。运用SystemView软件对该系统模型的电路实现进行了设计分析。对该系统性能从时域、功率谱等视角进行了实验研究,验证了所设计电路系统的正确性。
The paper studied the model of digital signal transmission, and detailedly discuses the raised cosine frequency spectrum mathematical principle of transition characteristic of filter. The circuit of the system model was designed and analyzed by SystemView software. The performance of the system was experimental study from the aspect of time domain and power spectrum. The experimental results shows that are correct.
