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。
The content of this theme is as follows : without time , without open , without stopping railway transport , and without interrupting traction current of block tested , meanwhile track circuit parameters in electrical and no electrical blocks is measured of on - line , dynamic and real - time . these parameters include voltage of fsk signal , voltage of industrial and harmonic wave interference , upper frequency , lower frequency , carrier frequency and low frequency 18 messages frequency
本课题研究内容：在不要点，不开天窗，不中断行车，不中断被测区段牵引电流的情况下，在线、动态、实时测量电化区段和非电化区段的移频信号电压、工频干扰电压，移频信号（调频信号）的上边频、下边频、载波频率、以及低频18信息频率等参数。
