您要查找的是不是：
- Reference Frequency Unit 基准频率单位
- What is the reference frequency or range of reference frequency? 参考时钟频率多少?
- Opto-electronic oscillator(OEO) is a hybrid optical electrical device featured with a loop structure and high speed performance. As a kind of oscillator,the oscillation of OEO can be injection locked by an external reference frequency. 本文所研究的光电振荡器（OEO）是一种高速光电混合环路;其振荡频率可以被锁定于外界信号的数据率.
- The complex weighting vectors at other frequencies satisfying the request of wideband constant beamwidth can be deduced from the one at the reference frequency. 其它频率点上满足宽带恒定束宽要求的复权向量可以根据参考频率上的复数权值通过折算求得。
- IRFU Integrated Radio Frequency Unit 综合无线电频率单位
- A unit of frequency equal to one cycle per second. 赫兹频率的单位，等于每秒一周
- Don't refer to this matter again, please. 请不要再提这件事了。
- SRFM Signal Reference Frequency Multiplex 信号参考频率复用
- Target Doppler Reference Frequency 目标多普勒基准频率
- combined reference frequency system 组合参考频率系统
- As the referenced frequency is fixed, the output frequency, the phase quantization noise and the resolution of frequency and phase are due to frequency word, the value of ROM and the bits of D/A converter, the bits of accumulator and ROM respectively. 时钟频率给定后,输出信号的频率取决于频率控制字,频率分辨率取决于累加器位数,相位分辨率取决于ROM的地址线位数,幅度量化噪声取决于ROM的数据位字长和D/A转换器位数。
