The next part discussed some constraint condition for design torque-rebalance pulse width modulated servo system. 第二部分讨论设计力矩再平衡脉冲调宽伺服系统中的某些限制条件;
In this paper, fundamental principle is presented to calibrate broad_band sampling oscilloscopes using pulse standards at the first. Next, a fast_pulse oscilloscope calibration system is presented that is based on pulse standard. Finally, the results of computer simulation are given. 本文首先介绍了用脉冲标准法校准取样示波器的基本原理,其次介绍了基于脉冲标准法的快速脉冲示波器校准系统(FPOCS),最后给出了计算机的仿真结果。
Next to that, the single pulse energy of independent pulse generator is analyzed, it found that isopulse mode can control the energy accurately and suits for micro-EDM. 然后,通过对独立式脉冲电源单次脉冲放电能量分析发现,等脉冲模式能够精确控制单脉冲能量,非常适合于微细电火花加工。
The results of pulsed electrodeposition show that there exists a relaxation time which is beneficial to the growth of HAP, due to it enables ions diffuse from bulk to the surface of electrode and reduce concentration polarization in the next pulse time. 结果表明:由于脉冲电沉积的一个关断时间使离子得以从溶液本体向电极表面扩散,在下一脉冲来临时浓差极化的减小有利于HAP的生长;
First on the production site, the pulse response of generalized object was measured on line, next, the mathematical model of the controlled object was determined according to pulse response. 首先在生产现场测得的广义对象的阶跃响应曲线,再由该曲线确定被控对象的数学模型。
If we can get the input and output signal data of the measurement system, then input these data to the program, we will get the mathematic model. Next, we can easily reconstruction the real nanosecond pulse. 只要获得测量系统的输入输出信号数据,输入到程序中,就可以辨识出测量系统的数学模型,进一步实现波形重建。
In this dissertation, it uses the instantaneous correlation algorithm. It can gain a high recognition rate of signals with less operation. Next, it introduces the extraction method of the time-domain parameters such as pulse width, pulse repetition rate and pulse range. 在以后的章节中,本文将采用基于瞬时自相关的瞬时频率提取方法,该算法运算量小,提取速度快。接下来介绍了雷达脉冲的宽度、重复间隔和幅度等时域参数提取方法。
