Abstract：Considering the characteristic of frequency shift keying(FSK)signal transmitted in the track circuit of electrified railway and high speed railway,a DSP(Digital Signal Processor) based real time automatic information test system is developed.Based on the analysis of the frequency spectrum of FSK signal,a FFT(Fast Fourier Transforms) based frequency measuring scheme is determined.
Keywords：digital signal processor fast fourier transform frequency shift keying signal real time test
