求翻译：而直接数字频率合成DDS(Direct Digital Frequency Synthesizer)的出现恰好可以弥补这一缺陷，具有高稳定性、大功率、频率、相位范围可调等特点[8][9][10]。为此，提出了一种基于DDS技术的电磁波数字发射电路。是什么意思？

The direct digital frequency synthesizer DDS (Direct Digital Frequency Synthesizer) just can make up the appearance of this defect, high stability, high-power, frequency, phase adjustable range of characteristics [8] [9] [10]. In this paper, based on DDS technology of the digital transmitter of elec

While direct digital frequency synthesis (Direct DDS Digital Frequency Synthesizer exactly the emergence) can compensate for this deficiency, with high stability, high power, frequency, phase-scope features such as adjustable [ 8] [ 9] [ 10 ]. To this end, the idea of a technology-based electromagne

But the direct digital frequency synthesizes DDS (Direct Digital Frequency Synthesizer) the appearance may make up this flaw exactly, has the high stability, the high efficiency, the frequency, the phase scope adjustable and so on characteristic (8)(9)(10).Therefore, proposed one kind based on the D

Direct digital frequency synthesizer DDS (Direct Digital Frequency Synthesizer) appears exactly can compensate for this shortcoming, with high stability, high power, frequency, phase scope, such as adjustable characteristics [8][9][10]. To this end, have come up with a digital transmitter based on D

And the appearance that the digital frequency formates DDS (Direct Digital Frequency Synthesizer) happens that be able to remedy this defect directly, the characteristic [8 ] that high stability, high-power, frequency, phase place scope are adjustable,etc. [9 ] [10 ]. For this reason, have proposed
