例句与用法

1. The method is to judge whether a system is stable by analyzing the amplification of loop circuit based on amplitude frequency response and phase frequency or not
   这种方法是将电路的幅频特性和相频特性曲线结合起来对环路增益进行分析，以此作为判断系统是否稳定的依据。
2. The traditional analog frequency - sweeping instrument , which mostly uses the lc circuit as the frequency oscillator , is more expensive , too much bigger and heavy to carry . it can only display the curve of amplitude - frequency , but ca n ' t used to measure the phase - frequency , and ca n ' t used to print the curve of frequency response characteristic either . it brings many discommodity to the user
   传统的模拟式扫频仪大多是用lc电路构成扫频振荡器,它不仅价格昂贵,体积庞大,而且只能显示幅频特性曲线,不能得到相频特性曲线,更不能打印被测网络的频响曲线,给使用者带来诸多不便。
3. In the end , the main content of this dissertation is addressed . in chapter 2 , based on the analysis of present vibrator ' s principle and structure , two kinds of transfer functions and frequency response curves of the vibrator , driven by voltage feedback power amplifier and current feedback amplifier , are given separately . and turnover frequencies between different frequency rangs are also given
