摘要
文章介绍了3种宽带数字储频的基本结构,分析了宽带数字储频的一个重要指标——量化噪声,根据输出信号频谱的杂散电平比较了三种结构的优劣。
This paper introduces three basic structures about digital radio frequency memory ( DRFM ) and analyses noise encoded which is one of important index of the DRFM, comparing these structures according to the spectral impurities of the output spectrum.
