This instrument can measure ac signal frequency either of the single phase voltage or of the tri - phase voltage 本表既可测交流单相电压信号之频率,亦可测交流三相电压信号之频率。
In pulse code modulation , a spurious signal formed from beats between the signal frequency and the sample frequency 在脉冲编码调制中,信号频率和取样频率之间的差拍所引起的伪信号。
The high permeability of the ferromagnetic reeds in a reed relay causes a pronounced skin effect with increasing signal frequency 干簧式继电器中铁磁簧片的高磁导率会随信号频率的增加而产生很强的趋肤效应。
For example , when the speed of transporting is very low , it is very difficult to track the receiver signal frequency through the common phase locked loop 如在传输数据速率较低时,普通锁相环来跟踪接收信号频率则很困难。
