| 摘 要： | 讨论了连续相位移频信号的时域与频域特性,并给出中心频率分量的相对幅度。为了设计出铁路专用连续相位的移频信号,利用美国德州仪器(TI)16位超低功耗单片机MSP430系列单片机控制AD9832产生连续相位的FSK移频信号,并用铁路专用ZPW2000测试仪表进行了测量,测量结果表明,无论是载频还是低频,误差均不大于0.05 Hz,完全满足铁路移频误差不大于0.1 Hz的要求,为铁路运输提供理论和实践应用。

| Abstract: | This paper discusses the continuous phase displacement frequency signal of the time domain and frequency domain properties, and give center frequency component of relative amplitude. In order to design a railway special continuous phase frequency shift signal, this paper use the United States Texas instruments (TI) 16 ultra-low power MSP430 MCU series single-chip microcomputer to control AD9832 produce continuous phase frequency shift of FSK signal.And use railway ZPW2000 test instrument for the measurement and the analysis measuring results show that, whether the carrier frequency or low frequency, the error is not more than 0.05 Hz, completely meet the railway frequency shift error is not more than 0.1 Hz requirements. And for the railway transport provide theory and practice. |
