本文对几种幅度调制波信号的欠采样频率的选择方法及恢复方法进行了研究 .这种方法可直接得到原信号而不需要解调电路 ,是欠采样方法应用的实例 .
In this paper, the methods of selecting and recovering the undersampled frequencies of several amplitude modulated wave signals are studied, which can directly obtain the original signal without the need of demodulation circuit, which is an example of the application of undersampling method.
