交流信号 meaning in English
ac signal
alternate current signal
Examples
- Development of an alternating message source for the experiment of simulated static electric field tracing
用模拟法描绘静电场实验中交流信号源的研制 - A novel digital watermarking scheme based on synthesis and separation method of direct and alternating signal is proposed in chapter 4
第四章根据直流和交流信号的合成和分离方法,探索了一条频率域鲁棒性水印的新思路。 - The results show that this testing system is fit for the test of dc signals , lower frequency signals and power frequency signals
结果表明，该测试系统不仅适合于直流信号的测试，而且同样适合于低频信号、工频交流信号的测试。 - The instrument is made up of an oscillating detector , which converts the distributed voltage of an insulator to ac signal for further treatment , a singlechip - microcomputer unit and a speaker system
仪器采用振动式探头，把绝缘子的直流电压变成交流信号，处理后，语音直接报出绝缘子的电压值。 - 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。
