To minimize computer requirements, system frequency response is often compromised . 为了尽量减少计算机的工作量,需要分析系统的频率响应特性。
Gets the raw system frequency 获取原始系统频率。
According to the best selected parameters , it gave the system frequency speciality and dynamic performance 根据所选最佳参数进行仿真,给出系统的频率特性及动态性能指标。
In this paper , a firing - pulse generator based on measuring ac system frequency is presented . a modern programmable asic fpga is used to build logical circuits 本文比较了逻辑图输入法和vhdl设计法这两种集成电路的设计方法,最后选用vhdl来设计fpga芯片。
Computer simulation indicates , the algorithm can follow the change of system frequency well and carry on the tracking measurement of frequency on the multiple signals at the same time 计算机仿真结果表明,本算法能较好地跟踪系统频率的变化,能够同时对多路信号进行频率的跟踪测量。
