1)  admixture-frequency syntheses
混合式频率合成法
2)  admixture frequency synthesize technique
混合式频率合成技术
1.
The pure DDS frequency synthesizes or the traditional PLL frequency synthesizes has one′s own strong points and disadvantages,making use of the admixture frequency synthesize technique,we can combine the two synthesis techniques and live up to learn from others′s strong points to offset one′s weakness.
单纯的DDS技术在与PLL技术在频率合成应用中各有优缺点,采用混合式频率合成技术可以将两者结合,做到取长补短。
3)  frequency composition method
频率合成法
4)  frequency synthesizer including mixer
含混频器的频率合成器
1.
The influence of mixer spurious on output frequency spectrum of a frequency synthesizer including mixer is analyzed in detail,and the calculation formula of spurious component S_I(Ω_i) in output frequency spectrum of frequency synthesizer due to mixer spurious is derived.
详细讨论了含混频器的频率合成器中混频器杂散对频率合成器输出频谱的影响,并导出了频率合成器输出频谱中由混频器杂散引起的杂散分量SI(Ωi)的计算公式,从而为含混频器的频率合成器抑制混频器引起的频谱杂散分量提供了理论依据和技术途径。
5)  digital frequency synthesize
数字式频率合成
6)  PLL synthesis
锁相式频率合成
