尖峰脉冲 meaning in English
spike pulse
Examples
- What have made a large amount of harmonic and high electro - magnetic interference ( emi ) has two reasons . the first reason is mainly the hard - switching pwm mode . the switch turns on at high voltage and turns off at high current in a short time ( ns ) , which leads to a high du / dt and di / dt and emi
其原因一是由于硬开关的pwm调节方式,电子开关速度很快( ns数量级)在高电压下导通,大电流下关断,导致很高的du dt和di dt ,产生很强的尖峰脉冲,对周围环境造成电磁干扰。 - In hardware , we choose anti - disturbance photoelectric isolative sensor , take rc filter to resolve high - frequency for anti - disturbance . in software , we adopt arithmetic of recursion mean value to collective signal values to resolve low - frequency ac and pinnacle pulse disturbance
在硬件方面,选用抗干扰能力强的光电隔离电量传感器,并采取rc滤波抗干扰措施解决中高频干扰问题;在软件方面,对采集到的信号量采取递推平均值算法,解决低频交流和尖峰脉冲干扰问题。 - Simulations on light intensity are validated by experiments and influence of mechanical dither on gyro frequency stabilization is studied for the first time . then it is point out that the key to improve the precision of frequency stabilization is to choose appropriate modulation frequency based on the frequency spectrum of sharp pulses , which is introduced by mechanical dither . thereafter , experiments of frequency stabilization under different modulation frequencies are made
通过实验验证了光强仿真结果,首次分析了机械抖动对稳频的影响,指出提高机抖陀螺小抖动稳频精度的关键在于:根据机械抖动引入的交流光强尖峰脉冲频谱分布选择合适的调制频率,并给出了不同调制频率的稳频实验结果。 - Secondly , considering the need of frequency stabilization , mdrlg ' s light intensity is simulated . the simulations indicate that sharp pulses are produced in the ac light intensity by mechanical dither . as the pulses have a wide frequency spectrum and range over the modulation frequencies of frequency stabilization , mechanical dither may reduce the precision of frequency stabilization
其次,根据稳频需要对机抖陀螺输出光强进行了仿真,仿真表明机械抖动会在交流光强中引入尖峰脉冲,且尖峰脉冲频谱分布较宽,在小抖动稳频调制频率范围内有功率输出,因而可能降低稳频精度。
