  • 調(diào)制頻率

Examples

  • 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
    在測量移頻信號(hào)的上、下邊頻及載波頻率時(shí),采用直接測量上、下邊頻,然后由上、下邊頻求中頻載波的方法。
  • 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
    該電源具有如下特點(diǎn):可以輸出單極性、雙極性和混合極性spwm波;可以輸出方波;可調(diào)頻調(diào)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
    運(yùn)用該變換從信號(hào)本身的尺度特征出發(fā)對(duì)信號(hào)進(jìn)行分解的特點(diǎn),對(duì)輸入信號(hào)進(jìn)行自適應(yīng)的頻帶劃分,從而求出了閃變的調(diào)制信號(hào)幅值和調(diào)制頻率;利用該方法中的瞬時(shí)頻率概念,從時(shí)頻兩方面同時(shí)對(duì)信號(hào)進(jìn)行分析,從而獲得了閃變信號(hào)的發(fā)生時(shí)刻和終止時(shí)刻,得到了較好的檢測效果。
  • 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
    與傳統(tǒng)的相位法測距相比,本方法使用單調(diào)制頻率實(shí)現(xiàn)了多頻測距,有效地解決了相位法測距中測程與測量精度之間的矛盾,具有高精度、大量程、大噪聲容限的特點(diǎn),而且簡化了硬件設(shè)計(jì),降低了成本;其次在數(shù)據(jù)處理中采用數(shù)據(jù)加窗函數(shù)的方法,提高了方波信號(hào)的頻譜分辨率,進(jìn)而提高了測量的精度。
