Abstract :
In this paper, a virtual instrument simulation system is developed for the railway FSK signal. The system can generate FSK signals with different carrier frequencies, base frequencies and frequency offsets. Some commonly used signal processing methods of the FSK signal, such as spectrum, zoom spectrum and under-sampling spectrum are also included in this virtual instrument system. People can use it to simulate different working conditions in the real word.
