lpf meaning in Chinese
白细胞增多促进因子,升高白细胞促进因子
促白细胞增多因子
低通滤波器
Examples
- An lpf can be simulated by setting the bpf ' s centre frequency to zero
将带通滤波器的中心频率设置到0 ，就可以模拟低通滤波器。 - Lpf low pass filter
低通滤波器 - Under special conditions a bpf may also be used as an lpf or as an hpf
在特殊条件下，带通滤波器也可以用作低通滤波器或高通滤波器。 - This is because the bpf is a two - pole filter ; at its cut - off frequency ( when output is 50 per cent ) the output power of a true lpf of the same cut - off would be in fact 70 . 7 per cent
这是因为带通滤波器是一个两极滤波器；在其截止频率下（输出为50 % ） ，真正的具有相同截止频率的低通虑波器的输出功率事实上为70 . 7 % 。 - The paper designs a more lpf and a numberical filter to eliminate the error , and a frequency tracing tache because system frequency fluctuates ceaselessly . this guarantes synchronization sampling
为了消除频率混叠带来的误差，专门设计具有较好性能的低通滤波器和数字滤波器；由于系统频率波动性，设计有硬件电路组成的频率跟踪环节，最终实现采样周期和信号周期同步。
