Examples
- Digital phase shift signal generator
数字式移相信号发生器 - The practice of doppler frequency - shift signal extraction in ultrasonic blood flow detector
多普勒频移信号提取技术在超声血流检测中应用 - In this paper , we analyze the reason that it is difficult to process the doppler frequency shift signal generated by low velocity moving target and discuss the kalmus filter performances for low velocity moving target detection
本文分析了低速目标的多普勒频移信号难以处理的原因，并讨论了kalmus滤波器（零速率波器）对低速运动目标的检测性能。 - Because frequency - shift signal is a kind of modulation signal , it ' s waveform is two ac sine signal of alternating i . e . upper frequency and lower frequency which was generated by low frequency modulating middle frequency
由于移频信号是一种调频信号，其波形为低频信号调制中心载频信号后产生的低端载频（下边频）和高端载频（上边频）两个交替变化的正弦交流信号。 - 2 . based on interoferometric technique , a parasitic interference configuration was introduced to transpose the wavelength - shift signal into phase - shift signal ; the strains were demodulated by measuring the phase change of the signal with a phase - meter
利用干涉技术，采用寄生干涉结构对传感光栅的反射谱进行波长解码，用相位计观测波长漂移引起干涉仪两臂间相位差的变化，进而监测作用在传感光栅上的待测应变量。
