reference frequency meaning in Chinese
标准测试频率
基准频率, 参考频率
Examples
- Dds is used to achieve fine resolution , while injection phase lock circuit is used to realize low phase noise high performance input reference frequency
Dds用于实现小步进,而注入锁相电路则用来产生低相噪的高性能参考源。 - The equivalent cavity model is used to deduce the threshold condition of the ecld , and the expression of the threshold carrier density n ( v ) when ecld is tuned to oscillate at different frequencies has been obtained . using the expression of n ( v ) and the carrier dependent refractive index , the simple basic equation describing the bistable characteristics has been derived after choosing an appropriate reference frequency nf
通过建立等效腔模型来推导外腔半导体激光器的阈值条件，得到ecld在不同频率v振荡所需的阈值载流子密度n ( v )表达式，利用该表达式及相关的折射率表达式，在选择合适的参考载流子密度n _ f后，导出了一个描述双稳所需的基本方程。 - Analog temperature compensation crystal oscillator ( atcxo ) is widely used in electronic equipments such as communications , navigation , radar , mobile telephone , program control telephone , measure instruments etc . as their reference frequency source , it is critical part of the above equipments , called as their “ heart ”
模拟温度补偿晶体振荡器( atcxo )广泛应用于通信、导航、雷达、移动通信、程控电话、测量仪器等电子设备中。作为基准频率源,它是上述电子设备的关键部件,被称为此类电子设备的“心脏” 。
