Nyquist图
1.
Based on the investigation for the relationship between the change rate of the phase angle of a Nyquist plot (CRPA) and the poles of the open-loop system or the closed-loop system, the main regions, in which the frequencies of mechanical oscillation modes lie, are determined and their relevant characteristics with the generators are given using the extreme .

In this article,the authors use C++ and C to compile programs to design a set of computer aided instruction software of drawing methods concerned with frequency response characteristics——the NYQUIST plot and the BODE plot.
采用C+ + 和C混合编程设计了一套有关频率响应特性———NYQUIST图和BODE 图绘图方法的辅助教学软件。
5) Nyquist approach
Nyquist法
6) Nyquist rate
Nyquist率
1.
According to Shannon sampling theorem, however, sampling rate should not be smaller than Nyquist rate, which means that UWB signals have to be sampled at a quite high sampling rate and non-bandlimited signals can not be reconstructed exactly.
根据Shannon采样定理，对信号的采样率不能低于Nyquist率，这就意味着对超宽带信号采样需要很高的采样率，而对于非带限信号更是无法通过采样点准确重建原始信号。
