• In testing upper frequency , lower frequency , and modulating frequency , the method of directly testing upper frequency and lower frequency then calculating carrier frequency is adopted
  在测量移频信号的上、下边频及载波频率时，采用直接测量上、下边频，然后由上、下边频求中频载波的方法。
• The power includes the following characters : being able to output signal - pole , double - pole and multi - pole spwm waves ; being able to output square wave ; being able to modulate frequency and modulate output voltage range
  该电源具有如下特点：可以输出单极性、双极性和混合极性spwm波；可以输出方波；可调频调幅。
• The transform uses the scale of the signal to decompose and make self - adapting frequency band partition of the input signals . therefore the amplitude value and the modulating frequency of the flickering signal can be obtained . with the instantaneous frequency in this method , the present study also analyzes the signal in terms of both time and frequency , and thus gets the time at which the flickering signal occurs and terminates
  运用该变换从信号本身的尺度特征出发对信号进行分解的特点,对输入信号进行自适应的频带划分,从而求出了闪变的调制信号幅值和调制频率;利用该方法中的瞬时频率概念,从时频两方面同时对信号进行分析,从而获得了闪变信号的发生时刻和终止时刻,得到了较好的检测效果。
• Comparing with the traditional phase - shifted laser range finder , the method could implement the ranging with multifrequency by using single modulated frequency . it could not only solve the contradiction of the range and the precision , but has high degree of accuracy and wide range , simplify the hardware design , and reduce the cost . this paper introduced the theory of phase distance measurement , analyzed various testing methods and expatiated the hardware and the software for the proposal system
  与传统的相位法测距相比，本方法使用单调制频率实现了多频测距，有效地解决了相位法测距中测程与测量精度之间的矛盾，具有高精度、大量程、大噪声容限的特点，而且简化了硬件设计，降低了成本；其次在数据处理中采用数据加窗函数的方法，提高了方波信号的频谱分辨率，进而提高了测量的精度。
