| Abstract: | With the development of the high speed railway and the widely use of jointlessfrequency- shift track circuit. The measurement of wayside signals needs higher accuracy.The automatic measuring system is analyzed in this paper, which implements with high speedsignal processor TMS320C25 and TMC2310 as the kernel component. It has many advantagesl such as complete functions and high stabillty. The frequency spectrum of frequencyshift signal is also analyzed. The sample frequency of narrow signal is determined. |
