摘要
根据对常规调制解调信号频谱的分析,提出了一种基于采样和数字滤波的方法,这种方法不仅能很大地降低信号的失真,而且便于DSP计算和计算机处理。
According to the analysis on the spectrum of the signals of the conv entional modem, this paper puts forward a method based on the sampling and digit al filtering, which can not only reduce the distortion of the signals but also b e convenient for the DSP calculation and the computer treatment.
